# `pathlib` — Object-oriented filesystem paths

Added in version 3.4.

Source code: Lib/pathlib/

This module offers classes representing filesystem paths with semantics appropriate for different operating systems. Path classes are divided between pure paths, which provide purely computational operations without I/O, and concrete paths, which inherit from pure paths but also provide I/O operations.

If you’ve never used this module before or just aren’t sure which class is right for your task, `Path` is most likely what you need. It instantiates a concrete path for the platform the code is running on.

Pure paths are useful in some special cases; for example:

1. If you want to manipulate Windows paths on a Unix machine (or vice versa). You cannot instantiate a `WindowsPath` when running on Unix, but you can instantiate `PureWindowsPath`.

2. You want to make sure that your code only manipulates paths without actually accessing the OS. In this case, instantiating one of the pure classes may be useful since those simply don’t have any OS-accessing operations.

For low-level path manipulation on strings, you can also use the `os.path` module.

## Basic use

Importing the main class:

    >>> from pathlib import Path

Listing subdirectories:

    >>> p = Path('.')
    >>> [x for x in p.iterdir() if x.is_dir()]
    [PosixPath('.hg'), PosixPath('docs'), PosixPath('dist'),
     PosixPath('__pycache__'), PosixPath('build')]

Listing Python source files in this directory tree:

    >>> list(p.glob('**/*.py'))
    [PosixPath('test_pathlib.py'), PosixPath('setup.py'),
     PosixPath('pathlib.py'), PosixPath('docs/conf.py'),
     PosixPath('build/lib/pathlib.py')]

Navigating inside a directory tree:

    >>> p = Path('/etc')
    >>> q = p / 'init.d' / 'reboot'
    >>> q
    PosixPath('/etc/init.d/reboot')
    >>> q.resolve()
    PosixPath('/etc/rc.d/init.d/halt')

Querying path properties:

    >>> q.exists()
    True
    >>> q.is_dir()
    False

Opening a file:

    >>> with q.open() as f: f.readline()
    ...
    '#!/bin/bash\n'

## Exceptions

exception pathlib.UnsupportedOperation

  An exception inheriting `NotImplementedError` that is raised when an unsupported operation is called on a path object.

  Added in version 3.13.

## Pure paths

Pure path objects provide path-handling operations which don’t actually access a filesystem. There are three ways to access these classes, which we also call flavours:

class pathlib.PurePath(*pathsegments)

  A generic class that represents the system’s path flavour (instantiating it creates either a `PurePosixPath` or a `PureWindowsPath`):

      >>> PurePath('setup.py')      # Running on a Unix machine
      PurePosixPath('setup.py')

  Each element of pathsegments can be either a string representing a path segment, or an object implementing the `os.PathLike` interface where the `__fspath__()` method returns a string, such as another path object:

      >>> PurePath('foo', 'some/path', 'bar')
      PurePosixPath('foo/some/path/bar')
      >>> PurePath(Path('foo'), Path('bar'))
      PurePosixPath('foo/bar')

  When pathsegments is empty, the current directory is assumed:

      >>> PurePath()
      PurePosixPath('.')

  If a segment is an absolute path, all previous segments are ignored (like `os.path.join()`):

      >>> PurePath('/etc', '/usr', 'lib64')
      PurePosixPath('/usr/lib64')
      >>> PureWindowsPath('c:/Windows', 'd:bar')
      PureWindowsPath('d:bar')

  On Windows, the drive is not reset when a rooted relative path segment (e.g., `r'\foo'`) is encountered:

      >>> PureWindowsPath('c:/Windows', '/Program Files')
      PureWindowsPath('c:/Program Files')

  Spurious slashes and single dots are collapsed, but double dots (`'..'`) and leading double slashes (`'//'`) are not, since this would change the meaning of a path for various reasons (e.g. symbolic links, UNC paths):

      >>> PurePath('foo//bar')
      PurePosixPath('foo/bar')
      >>> PurePath('//foo/bar')
      PurePosixPath('//foo/bar')
      >>> PurePath('foo/./bar')
      PurePosixPath('foo/bar')
      >>> PurePath('foo/../bar')
      PurePosixPath('foo/../bar')

  (a naïve approach would make `PurePosixPath('foo/../bar')` equivalent to `PurePosixPath('bar')`, which is wrong if `foo` is a symbolic link to another directory)

  Pure path objects implement the `os.PathLike` interface, allowing them to be used anywhere the interface is accepted.

  Changed in version 3.6: Added support for the `os.PathLike` interface.

class pathlib.PurePosixPath(*pathsegments)

  A subclass of `PurePath`, this path flavour represents non-Windows filesystem paths:

      >>> PurePosixPath('/etc/hosts')
      PurePosixPath('/etc/hosts')

  pathsegments is specified similarly to `PurePath`.

class pathlib.PureWindowsPath(*pathsegments)

  A subclass of `PurePath`, this path flavour represents Windows filesystem paths, including UNC paths:

      >>> PureWindowsPath('c:/', 'Users', 'Ximénez')
      PureWindowsPath('c:/Users/Ximénez')
      >>> PureWindowsPath('//server/share/file')
      PureWindowsPath('//server/share/file')

  pathsegments is specified similarly to `PurePath`.

Regardless of the system you’re running on, you can instantiate all of these classes, since they don’t provide any operation that does system calls.

### General properties

Paths are immutable and hashable. Paths of a same flavour are comparable and orderable. These properties respect the flavour’s case-folding semantics:

    >>> PurePosixPath('foo') == PurePosixPath('FOO')
    False
    >>> PureWindowsPath('foo') == PureWindowsPath('FOO')
    True
    >>> PureWindowsPath('FOO') in { PureWindowsPath('foo') }
    True
    >>> PureWindowsPath('C:') < PureWindowsPath('d:')
    True

Paths of a different flavour compare unequal and cannot be ordered:

    >>> PureWindowsPath('foo') == PurePosixPath('foo')
    False
    >>> PureWindowsPath('foo') < PurePosixPath('foo')
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    TypeError: '<' not supported between instances of 'PureWindowsPath' and 'PurePosixPath'

### Operators

The slash operator helps create child paths, like `os.path.join()`. If the argument is an absolute path, the previous path is ignored. On Windows, the drive is not reset when the argument is a rooted relative path (e.g., `r'\foo'`):

    >>> p = PurePath('/etc')
    >>> p
    PurePosixPath('/etc')
    >>> p / 'init.d' / 'apache2'
    PurePosixPath('/etc/init.d/apache2')
    >>> q = PurePath('bin')
    >>> '/usr' / q
    PurePosixPath('/usr/bin')
    >>> p / '/an_absolute_path'
    PurePosixPath('/an_absolute_path')
    >>> PureWindowsPath('c:/Windows', '/Program Files')
    PureWindowsPath('c:/Program Files')

A path object can be used anywhere an object implementing `os.PathLike` is accepted:

    >>> import os
    >>> p = PurePath('/etc')
    >>> os.fspath(p)
    '/etc'

The string representation of a path is the raw filesystem path itself (in native form, e.g. with backslashes under Windows), which you can pass to any function taking a file path as a string:

    >>> p = PurePath('/etc')
    >>> str(p)
    '/etc'
    >>> p = PureWindowsPath('c:/Program Files')
    >>> str(p)
    'c:\\Program Files'

Similarly, calling `bytes` on a path gives the raw filesystem path as a bytes object, as encoded by `os.fsencode()`:

    >>> bytes(p)
    b'/etc'

Note

Calling `bytes` is only recommended under Unix. Under Windows, the unicode form is the canonical representation of filesystem paths.

### Accessing individual parts

To access the individual “parts” (components) of a path, use the following property:

PurePath.parts

  A tuple giving access to the path’s various components:

      >>> p = PurePath('/usr/bin/python3')
      >>> p.parts
      ('/', 'usr', 'bin', 'python3')

      >>> p = PureWindowsPath('c:/Program Files/PSF')
      >>> p.parts
      ('c:\\', 'Program Files', 'PSF')

  (note how the drive and local root are regrouped in a single part)

### Methods and properties

Pure paths provide the following methods and properties:

PurePath.parser

  The implementation of the `os.path` module used for low-level path parsing and joining: either `posixpath` or `ntpath`.

  Added in version 3.13.

PurePath.drive

  A string representing the drive letter or name, if any:

      >>> PureWindowsPath('c:/Program Files/').drive
      'c:'
      >>> PureWindowsPath('/Program Files/').drive
      ''
      >>> PurePosixPath('/etc').drive
      ''

  UNC shares are also considered drives:

      >>> PureWindowsPath('//host/share/foo.txt').drive
      '\\\\host\\share'

PurePath.root

  A string representing the (local or global) root, if any:

      >>> PureWindowsPath('c:/Program Files/').root
      '\\'
      >>> PureWindowsPath('c:Program Files/').root
      ''
      >>> PurePosixPath('/etc').root
      '/'

  UNC shares always have a root:

      >>> PureWindowsPath('//host/share').root
      '\\'

  If the path starts with more than two successive slashes, `PurePosixPath` collapses them:

      >>> PurePosixPath('//etc').root
      '//'
      >>> PurePosixPath('///etc').root
      '/'
      >>> PurePosixPath('////etc').root
      '/'

  Note

  This behavior conforms to The Open Group Base Specifications Issue 6, paragraph 4.11 Pathname Resolution:

  “A pathname that begins with two successive slashes may be interpreted in an implementation-defined manner, although more than two leading slashes shall be treated as a single slash.”

PurePath.anchor

  The concatenation of the drive and root:

      >>> PureWindowsPath('c:/Program Files/').anchor
      'c:\\'
      >>> PureWindowsPath('c:Program Files/').anchor
      'c:'
      >>> PurePosixPath('/etc').anchor
      '/'
      >>> PureWindowsPath('//host/share').anchor
      '\\\\host\\share\\'

PurePath.parents

  An immutable sequence providing access to the logical ancestors of the path:

      >>> p = PureWindowsPath('c:/foo/bar/setup.py')
      >>> p.parents[0]
      PureWindowsPath('c:/foo/bar')
      >>> p.parents[1]
      PureWindowsPath('c:/foo')
      >>> p.parents[2]
      PureWindowsPath('c:/')

  Changed in version 3.10: The parents sequence now supports slices and negative index values.

PurePath.parent

  The logical parent of the path:

      >>> p = PurePosixPath('/a/b/c/d')
      >>> p.parent
      PurePosixPath('/a/b/c')

  You cannot go past an anchor, or empty path:

      >>> p = PurePosixPath('/')
      >>> p.parent
      PurePosixPath('/')
      >>> p = PurePosixPath('.')
      >>> p.parent
      PurePosixPath('.')

  Note

  This is a purely lexical operation, hence the following behaviour:

      >>> p = PurePosixPath('foo/..')
      >>> p.parent
      PurePosixPath('foo')

  If you want to walk an arbitrary filesystem path upwards, it is recommended to first call `Path.resolve()` so as to resolve symlinks and eliminate `".."` components.

PurePath.name

  A string representing the final path component, excluding the drive and root, if any:

      >>> PurePosixPath('my/library/setup.py').name
      'setup.py'

  UNC drive names are not considered:

      >>> PureWindowsPath('//some/share/setup.py').name
      'setup.py'
      >>> PureWindowsPath('//some/share').name
      ''

PurePath.suffix

  The last dot-separated portion of the final component, if any:

      >>> PurePosixPath('my/library/setup.py').suffix
      '.py'
      >>> PurePosixPath('my/library.tar.gz').suffix
      '.gz'
      >>> PurePosixPath('my/library').suffix
      ''

  This is commonly called the file extension.

PurePath.suffixes

  A list of the path’s suffixes, often called file extensions:

      >>> PurePosixPath('my/library.tar.gar').suffixes
      ['.tar', '.gar']
      >>> PurePosixPath('my/library.tar.gz').suffixes
      ['.tar', '.gz']
      >>> PurePosixPath('my/library').suffixes
      []

PurePath.stem

  The final path component, without its suffix:

      >>> PurePosixPath('my/library.tar.gz').stem
      'library.tar'
      >>> PurePosixPath('my/library.tar').stem
      'library'
      >>> PurePosixPath('my/library').stem
      'library'

PurePath.as_posix()

  Return a string representation of the path with forward slashes (`/`):

      >>> p = PureWindowsPath('c:\\windows')
      >>> str(p)
      'c:\\windows'
      >>> p.as_posix()
      'c:/windows'

PurePath.is_absolute()

  Return whether the path is absolute or not. A path is considered absolute if it has both a root and (if the flavour allows) a drive:

      >>> PurePosixPath('/a/b').is_absolute()
      True
      >>> PurePosixPath('a/b').is_absolute()
      False

      >>> PureWindowsPath('c:/a/b').is_absolute()
      True
      >>> PureWindowsPath('/a/b').is_absolute()
      False
      >>> PureWindowsPath('c:').is_absolute()
      False
      >>> PureWindowsPath('//some/share').is_absolute()
      True

PurePath.is_relative_to(other)

  Return whether or not this path is relative to the other path.

      >>> p = PurePath('/etc/passwd')
      >>> p.is_relative_to('/etc')
      True
      >>> p.is_relative_to('/usr')
      False

  This method is string-based; it neither accesses the filesystem nor treats “`..`” segments specially. The following code is equivalent:

      >>> u = PurePath('/usr')
      >>> u == p or u in p.parents
      False

  Added in version 3.9.

  Deprecated since version 3.12, will be removed in version 3.14: Passing additional arguments is deprecated; if supplied, they are joined with other.

PurePath.is_reserved()

  With `PureWindowsPath`, return `True` if the path is considered reserved under Windows, `False` otherwise. With `PurePosixPath`, `False` is always returned.

  Changed in version 3.13: Windows path names that contain a colon, or end with a dot or a space, are considered reserved. UNC paths may be reserved.

  Deprecated since version 3.13, will be removed in version 3.15: This method is deprecated; use `os.path.isreserved()` to detect reserved paths on Windows.

PurePath.joinpath(*pathsegments)

  Calling this method is equivalent to combining the path with each of the given pathsegments in turn:

      >>> PurePosixPath('/etc').joinpath('passwd')
      PurePosixPath('/etc/passwd')
      >>> PurePosixPath('/etc').joinpath(PurePosixPath('passwd'))
      PurePosixPath('/etc/passwd')
      >>> PurePosixPath('/etc').joinpath('init.d', 'apache2')
      PurePosixPath('/etc/init.d/apache2')
      >>> PureWindowsPath('c:').joinpath('/Program Files')
      PureWindowsPath('c:/Program Files')

PurePath.full_match(pattern, *, case_sensitive=None)

  Match this path against the provided glob-style pattern. Return `True` if matching is successful, `False` otherwise. For example:

      >>> PurePath('a/b.py').full_match('a/*.py')
      True
      >>> PurePath('a/b.py').full_match('*.py')
      False
      >>> PurePath('/a/b/c.py').full_match('/a/**')
      True
      >>> PurePath('/a/b/c.py').full_match('**/*.py')
      True

  See also

  Pattern language documentation.

  As with other methods, case-sensitivity follows platform defaults:

      >>> PurePosixPath('b.py').full_match('*.PY')
      False
      >>> PureWindowsPath('b.py').full_match('*.PY')
      True

  Set case_sensitive to `True` or `False` to override this behaviour.

  Added in version 3.13.

PurePath.match(pattern, *, case_sensitive=None)

  Match this path against the provided non-recursive glob-style pattern. Return `True` if matching is successful, `False` otherwise.

  This method is similar to `full_match()`, but empty patterns aren’t allowed (`ValueError` is raised), the recursive wildcard “`**`” isn’t supported (it acts like non-recursive “`*`”), and if a relative pattern is provided, then matching is done from the right:

      >>> PurePath('a/b.py').match('*.py')
      True
      >>> PurePath('/a/b/c.py').match('b/*.py')
      True
      >>> PurePath('/a/b/c.py').match('a/*.py')
      False

  Changed in version 3.12: The pattern parameter accepts a path-like object.

  Changed in version 3.12: The case_sensitive parameter was added.

PurePath.relative_to(other, walk_up=False)

  Compute a version of this path relative to the path represented by other. If it’s impossible, `ValueError` is raised:

      >>> p = PurePosixPath('/etc/passwd')
      >>> p.relative_to('/')
      PurePosixPath('etc/passwd')
      >>> p.relative_to('/etc')
      PurePosixPath('passwd')
      >>> p.relative_to('/usr')
      Traceback (most recent call last):
        File "<stdin>", line 1, in <module>
        File "pathlib.py", line 941, in relative_to
          raise ValueError(error_message.format(str(self), str(formatted)))
      ValueError: '/etc/passwd' is not in the subpath of '/usr' OR one path is relative and the other is absolute.

  When walk_up is false (the default), the path must start with other. When the argument is true, `..` entries may be added to form the relative path. In all other cases, such as the paths referencing different drives, `ValueError` is raised.:

      >>> p.relative_to('/usr', walk_up=True)
      PurePosixPath('../etc/passwd')
      >>> p.relative_to('foo', walk_up=True)
      Traceback (most recent call last):
        File "<stdin>", line 1, in <module>
        File "pathlib.py", line 941, in relative_to
          raise ValueError(error_message.format(str(self), str(formatted)))
      ValueError: '/etc/passwd' is not on the same drive as 'foo' OR one path is relative and the other is absolute.

  Warning

  This function is part of `PurePath` and works with strings. It does not check or access the underlying file structure. This can impact the walk_up option as it assumes that no symlinks are present in the path; call `resolve()` first if necessary to resolve symlinks.

  Changed in version 3.12: The walk_up parameter was added (old behavior is the same as `walk_up=False`).

  Deprecated since version 3.12, will be removed in version 3.14: Passing additional positional arguments is deprecated; if supplied, they are joined with other.

PurePath.with_name(name)

  Return a new path with the `name` changed. If the original path doesn’t have a name, ValueError is raised:

      >>> p = PureWindowsPath('c:/Downloads/pathlib.tar.gz')
      >>> p.with_name('setup.py')
      PureWindowsPath('c:/Downloads/setup.py')
      >>> p = PureWindowsPath('c:/')
      >>> p.with_name('setup.py')
      Traceback (most recent call last):
        File "<stdin>", line 1, in <module>
        File "/home/antoine/cpython/default/Lib/pathlib.py", line 751, in with_name
          raise ValueError("%r has an empty name" % (self,))
      ValueError: PureWindowsPath('c:/') has an empty name

PurePath.with_stem(stem)

  Return a new path with the `stem` changed. If the original path doesn’t have a name, ValueError is raised:

      >>> p = PureWindowsPath('c:/Downloads/draft.txt')
      >>> p.with_stem('final')
      PureWindowsPath('c:/Downloads/final.txt')
      >>> p = PureWindowsPath('c:/Downloads/pathlib.tar.gz')
      >>> p.with_stem('lib')
      PureWindowsPath('c:/Downloads/lib.gz')
      >>> p = PureWindowsPath('c:/')
      >>> p.with_stem('')
      Traceback (most recent call last):
        File "<stdin>", line 1, in <module>
        File "/home/antoine/cpython/default/Lib/pathlib.py", line 861, in with_stem
          return self.with_name(stem + self.suffix)
        File "/home/antoine/cpython/default/Lib/pathlib.py", line 851, in with_name
          raise ValueError("%r has an empty name" % (self,))
      ValueError: PureWindowsPath('c:/') has an empty name

  Added in version 3.9.

PurePath.with_suffix(suffix)

  Return a new path with the `suffix` changed. If the original path doesn’t have a suffix, the new suffix is appended instead. If the suffix is an empty string, the original suffix is removed:

      >>> p = PureWindowsPath('c:/Downloads/pathlib.tar.gz')
      >>> p.with_suffix('.bz2')
      PureWindowsPath('c:/Downloads/pathlib.tar.bz2')
      >>> p = PureWindowsPath('README')
      >>> p.with_suffix('.txt')
      PureWindowsPath('README.txt')
      >>> p = PureWindowsPath('README.txt')
      >>> p.with_suffix('')
      PureWindowsPath('README')

PurePath.with_segments(*pathsegments)

  Create a new path object of the same type by combining the given pathsegments. This method is called whenever a derivative path is created, such as from `parent` and `relative_to()`. Subclasses may override this method to pass information to derivative paths, for example:

      from pathlib import PurePosixPath

      class MyPath(PurePosixPath):
          def __init__(self, *pathsegments, session_id):
              super().__init__(*pathsegments)
              self.session_id = session_id

          def with_segments(self, *pathsegments):
              return type(self)(*pathsegments, session_id=self.session_id)

      etc = MyPath('/etc', session_id=42)
      hosts = etc / 'hosts'
      print(hosts.session_id)  # 42

  Added in version 3.12.

## Concrete paths

Concrete paths are subclasses of the pure path classes. In addition to operations provided by the latter, they also provide methods to do system calls on path objects. There are three ways to instantiate concrete paths:

class pathlib.Path(*pathsegments)

  A subclass of `PurePath`, this class represents concrete paths of the system’s path flavour (instantiating it creates either a `PosixPath` or a `WindowsPath`):

      >>> Path('setup.py')
      PosixPath('setup.py')

  pathsegments is specified similarly to `PurePath`.

class pathlib.PosixPath(*pathsegments)

  A subclass of `Path` and `PurePosixPath`, this class represents concrete non-Windows filesystem paths:

      >>> PosixPath('/etc/hosts')
      PosixPath('/etc/hosts')

  pathsegments is specified similarly to `PurePath`.

  Changed in version 3.13: Raises `UnsupportedOperation` on Windows. In previous versions, `NotImplementedError` was raised instead.

class pathlib.WindowsPath(*pathsegments)

  A subclass of `Path` and `PureWindowsPath`, this class represents concrete Windows filesystem paths:

      >>> WindowsPath('c:/', 'Users', 'Ximénez')
      WindowsPath('c:/Users/Ximénez')

  pathsegments is specified similarly to `PurePath`.

  Changed in version 3.13: Raises `UnsupportedOperation` on non-Windows platforms. In previous versions, `NotImplementedError` was raised instead.

You can only instantiate the class flavour that corresponds to your system (allowing system calls on non-compatible path flavours could lead to bugs or failures in your application):

    >>> import os
    >>> os.name
    'posix'
    >>> Path('setup.py')
    PosixPath('setup.py')
    >>> PosixPath('setup.py')
    PosixPath('setup.py')
    >>> WindowsPath('setup.py')
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "pathlib.py", line 798, in __new__
        % (cls.__name__,))
    UnsupportedOperation: cannot instantiate 'WindowsPath' on your system

Some concrete path methods can raise an `OSError` if a system call fails (for example because the path doesn’t exist).

### Parsing and generating URIs

Concrete path objects can be created from, and represented as, ‘file’ URIs conforming to RFC 8089.

Note

File URIs are not portable across machines with different filesystem encodings.

classmethod Path.from_uri(uri)

  Return a new path object from parsing a ‘file’ URI. For example:

      >>> p = Path.from_uri('file:///etc/hosts')
      PosixPath('/etc/hosts')

  On Windows, DOS device and UNC paths may be parsed from URIs:

      >>> p = Path.from_uri('file:///c:/windows')
      WindowsPath('c:/windows')
      >>> p = Path.from_uri('file://server/share')
      WindowsPath('//server/share')

  Several variant forms are supported:

      >>> p = Path.from_uri('file:////server/share')
      WindowsPath('//server/share')
      >>> p = Path.from_uri('file://///server/share')
      WindowsPath('//server/share')
      >>> p = Path.from_uri('file:c:/windows')
      WindowsPath('c:/windows')
      >>> p = Path.from_uri('file:/c|/windows')
      WindowsPath('c:/windows')

  `ValueError` is raised if the URI does not start with `file:`, or the parsed path isn’t absolute.

  Added in version 3.13.

Path.as_uri()

  Represent the path as a ‘file’ URI. `ValueError` is raised if the path isn’t absolute.

      >>> p = PosixPath('/etc/passwd')
      >>> p.as_uri()
      'file:///etc/passwd'
      >>> p = WindowsPath('c:/Windows')
      >>> p.as_uri()
      'file:///c:/Windows'

  For historical reasons, this method is also available from `PurePath` objects. However, its use of `os.fsencode()` makes it strictly impure.

### Expanding and resolving paths

classmethod Path.home()

  Return a new path object representing the user’s home directory (as returned by `os.path.expanduser()` with `~` construct). If the home directory can’t be resolved, `RuntimeError` is raised.

      >>> Path.home()
      PosixPath('/home/antoine')

  Added in version 3.5.

Path.expanduser()

  Return a new path with expanded `~` and `~user` constructs, as returned by `os.path.expanduser()`. If a home directory can’t be resolved, `RuntimeError` is raised.

      >>> p = PosixPath('~/films/Monty Python')
      >>> p.expanduser()
      PosixPath('/home/eric/films/Monty Python')

  Added in version 3.5.

classmethod Path.cwd()

  Return a new path object representing the current directory (as returned by `os.getcwd()`):

      >>> Path.cwd()
      PosixPath('/home/antoine/pathlib')

Path.absolute()

  Make the path absolute, without normalization or resolving symlinks. Returns a new path object:

      >>> p = Path('tests')
      >>> p
      PosixPath('tests')
      >>> p.absolute()
      PosixPath('/home/antoine/pathlib/tests')

Path.resolve(strict=False)

  Make the path absolute, resolving any symlinks. A new path object is returned:

      >>> p = Path()
      >>> p
      PosixPath('.')
      >>> p.resolve()
      PosixPath('/home/antoine/pathlib')

  “`..`” components are also eliminated (this is the only method to do so):

      >>> p = Path('docs/../setup.py')
      >>> p.resolve()
      PosixPath('/home/antoine/pathlib/setup.py')

  If a path doesn’t exist or a symlink loop is encountered, and strict is `True`, `OSError` is raised. If strict is `False`, the path is resolved as far as possible and any remainder is appended without checking whether it exists.

  Changed in version 3.6: The strict parameter was added (pre-3.6 behavior is strict).

  Changed in version 3.13: Symlink loops are treated like other errors: `OSError` is raised in strict mode, and no exception is raised in non-strict mode. In previous versions, `RuntimeError` is raised no matter the value of strict.

Path.readlink()

  Return the path to which the symbolic link points (as returned by `os.readlink()`):

      >>> p = Path('mylink')
      >>> p.symlink_to('setup.py')
      >>> p.readlink()
      PosixPath('setup.py')

  Added in version 3.9.

  Changed in version 3.13: Raises `UnsupportedOperation` if `os.readlink()` is not available. In previous versions, `NotImplementedError` was raised.

### Querying file type and status

Changed in version 3.8: `exists()`, `is_dir()`, `is_file()`, `is_mount()`, `is_symlink()`, `is_block_device()`, `is_char_device()`, `is_fifo()`, `is_socket()` now return `False` instead of raising an exception for paths that contain characters unrepresentable at the OS level.

Path.stat(*, follow_symlinks=True)

  Return an `os.stat_result` object containing information about this path, like `os.stat()`. The result is looked up at each call to this method.

  This method normally follows symlinks; to stat a symlink add the argument `follow_symlinks=False`, or use `lstat()`.

      >>> p = Path('setup.py')
      >>> p.stat().st_size
      956
      >>> p.stat().st_mtime
      1327883547.852554

  Changed in version 3.10: The follow_symlinks parameter was added.

Path.lstat()

  Like `Path.stat()` but, if the path points to a symbolic link, return the symbolic link’s information rather than its target’s.

Path.exists(*, follow_symlinks=True)

  Return `True` if the path points to an existing file or directory.

  This method normally follows symlinks; to check if a symlink exists, add the argument `follow_symlinks=False`.

      >>> Path('.').exists()
      True
      >>> Path('setup.py').exists()
      True
      >>> Path('/etc').exists()
      True
      >>> Path('nonexistentfile').exists()
      False

  Changed in version 3.12: The follow_symlinks parameter was added.

Path.is_file(*, follow_symlinks=True)

  Return `True` if the path points to a regular file, `False` if it points to another kind of file.

  `False` is also returned if the path doesn’t exist or is a broken symlink; other errors (such as permission errors) are propagated.

  This method normally follows symlinks; to exclude symlinks, add the argument `follow_symlinks=False`.

  Changed in version 3.13: The follow_symlinks parameter was added.

Path.is_dir(*, follow_symlinks=True)

  Return `True` if the path points to a directory, `False` if it points to another kind of file.

  `False` is also returned if the path doesn’t exist or is a broken symlink; other errors (such as permission errors) are propagated.

  This method normally follows symlinks; to exclude symlinks to directories, add the argument `follow_symlinks=False`.

  Changed in version 3.13: The follow_symlinks parameter was added.

Path.is_symlink()

  Return `True` if the path points to a symbolic link, `False` otherwise.

  `False` is also returned if the path doesn’t exist; other errors (such as permission errors) are propagated.

Path.is_junction()

  Return `True` if the path points to a junction, and `False` for any other type of file. Currently only Windows supports junctions.

  Added in version 3.12.

Path.is_mount()

  Return `True` if the path is a mount point: a point in a file system where a different file system has been mounted. On POSIX, the function checks whether path’s parent, `path/..`, is on a different device than path, or whether `path/..` and path point to the same i-node on the same device — this should detect mount points for all Unix and POSIX variants. On Windows, a mount point is considered to be a drive letter root (e.g. `c:\`), a UNC share (e.g. `\\server\share`), or a mounted filesystem directory.

  Added in version 3.7.

  Changed in version 3.12: Windows support was added.

Path.is_socket()

  Return `True` if the path points to a Unix socket (or a symbolic link pointing to a Unix socket), `False` if it points to another kind of file.

  `False` is also returned if the path doesn’t exist or is a broken symlink; other errors (such as permission errors) are propagated.

Path.is_fifo()

  Return `True` if the path points to a FIFO (or a symbolic link pointing to a FIFO), `False` if it points to another kind of file.

  `False` is also returned if the path doesn’t exist or is a broken symlink; other errors (such as permission errors) are propagated.

Path.is_block_device()

  Return `True` if the path points to a block device (or a symbolic link pointing to a block device), `False` if it points to another kind of file.

  `False` is also returned if the path doesn’t exist or is a broken symlink; other errors (such as permission errors) are propagated.

Path.is_char_device()

  Return `True` if the path points to a character device (or a symbolic link pointing to a character device), `False` if it points to another kind of file.

  `False` is also returned if the path doesn’t exist or is a broken symlink; other errors (such as permission errors) are propagated.

Path.samefile(other_path)

  Return whether this path points to the same file as other_path, which can be either a Path object, or a string. The semantics are similar to `os.path.samefile()` and `os.path.samestat()`.

  An `OSError` can be raised if either file cannot be accessed for some reason.

      >>> p = Path('spam')
      >>> q = Path('eggs')
      >>> p.samefile(q)
      False
      >>> p.samefile('spam')
      True

  Added in version 3.5.

### Reading and writing files

Path.open(mode='r', buffering=-1, encoding=None, errors=None, newline=None)

  Open the file pointed to by the path, like the built-in `open()` function does:

      >>> p = Path('setup.py')
      >>> with p.open() as f:
      ...     f.readline()
      ...
      '#!/usr/bin/env python3\n'

Path.read_text(encoding=None, errors=None, newline=None)

  Return the decoded contents of the pointed-to file as a string:

      >>> p = Path('my_text_file')
      >>> p.write_text('Text file contents')
      18
      >>> p.read_text()
      'Text file contents'

  The file is opened and then closed. The optional parameters have the same meaning as in `open()`.

  Added in version 3.5.

  Changed in version 3.13: The newline parameter was added.

Path.read_bytes()

  Return the binary contents of the pointed-to file as a bytes object:

      >>> p = Path('my_binary_file')
      >>> p.write_bytes(b'Binary file contents')
      20
      >>> p.read_bytes()
      b'Binary file contents'

  Added in version 3.5.

Path.write_text(data, encoding=None, errors=None, newline=None)

  Open the file pointed to in text mode, write data to it, and close the file:

      >>> p = Path('my_text_file')
      >>> p.write_text('Text file contents')
      18
      >>> p.read_text()
      'Text file contents'

  An existing file of the same name is overwritten. The optional parameters have the same meaning as in `open()`.

  Added in version 3.5.

  Changed in version 3.10: The newline parameter was added.

Path.write_bytes(data)

  Open the file pointed to in bytes mode, write data to it, and close the file:

      >>> p = Path('my_binary_file')
      >>> p.write_bytes(b'Binary file contents')
      20
      >>> p.read_bytes()
      b'Binary file contents'

  An existing file of the same name is overwritten.

  Added in version 3.5.

### Reading directories

Path.iterdir()

  When the path points to a directory, yield path objects of the directory contents:

      >>> p = Path('docs')
      >>> for child in p.iterdir(): child
      ...
      PosixPath('docs/conf.py')
      PosixPath('docs/_templates')
      PosixPath('docs/make.bat')
      PosixPath('docs/index.rst')
      PosixPath('docs/_build')
      PosixPath('docs/_static')
      PosixPath('docs/Makefile')

  The children are yielded in arbitrary order, and the special entries `'.'` and `'..'` are not included. If a file is removed from or added to the directory after creating the iterator, it is unspecified whether a path object for that file is included.

  If the path is not a directory or otherwise inaccessible, `OSError` is raised.

Path.glob(pattern, *, case_sensitive=None, recurse_symlinks=False)

  Glob the given relative pattern in the directory represented by this path, yielding all matching files (of any kind):

      >>> sorted(Path('.').glob('*.py'))
      [PosixPath('pathlib.py'), PosixPath('setup.py'), PosixPath('test_pathlib.py')]
      >>> sorted(Path('.').glob('*/*.py'))
      [PosixPath('docs/conf.py')]
      >>> sorted(Path('.').glob('**/*.py'))
      [PosixPath('build/lib/pathlib.py'),
       PosixPath('docs/conf.py'),
       PosixPath('pathlib.py'),
       PosixPath('setup.py'),
       PosixPath('test_pathlib.py')]

  See also

  Pattern language documentation.

  By default, or when the case_sensitive keyword-only argument is set to `None`, this method matches paths using platform-specific casing rules: typically, case-sensitive on POSIX, and case-insensitive on Windows. Set case_sensitive to `True` or `False` to override this behaviour.

  By default, or when the recurse_symlinks keyword-only argument is set to `False`, this method follows symlinks except when expanding “`**`” wildcards. Set recurse_symlinks to `True` to always follow symlinks.

  Raises an auditing event `pathlib.Path.glob` with arguments `self`, `pattern`.

  Changed in version 3.12: The case_sensitive parameter was added.

  Changed in version 3.13: The recurse_symlinks parameter was added.

  Changed in version 3.13: The pattern parameter accepts a path-like object.

  Changed in version 3.13: Any `OSError` exceptions raised from scanning the filesystem are suppressed. In previous versions, such exceptions are suppressed in many cases, but not all.

Path.rglob(pattern, *, case_sensitive=None, recurse_symlinks=False)

  Glob the given relative pattern recursively. This is like calling `Path.glob()` with “`**/`” added in front of the pattern.

  See also

  Pattern language and `Path.glob()` documentation.

  Raises an auditing event `pathlib.Path.rglob` with arguments `self`, `pattern`.

  Changed in version 3.12: The case_sensitive parameter was added.

  Changed in version 3.13: The recurse_symlinks parameter was added.

  Changed in version 3.13: The pattern parameter accepts a path-like object.

Path.walk(top_down=True, on_error=None, follow_symlinks=False)

  Generate the file names in a directory tree by walking the tree either top-down or bottom-up.

  For each directory in the directory tree rooted at self (including self but excluding ‘.’ and ‘..’), the method yields a 3-tuple of `(dirpath, dirnames, filenames)`.

  dirpath is a `Path` to the directory currently being walked, dirnames is a list of strings for the names of subdirectories in dirpath (excluding `'.'` and `'..'`), and filenames is a list of strings for the names of the non-directory files in dirpath. To get a full path (which begins with self) to a file or directory in dirpath, do `dirpath / name`. Whether or not the lists are sorted is file system-dependent.

  If the optional argument top_down is true (which is the default), the triple for a directory is generated before the triples for any of its subdirectories (directories are walked top-down). If top_down is false, the triple for a directory is generated after the triples for all of its subdirectories (directories are walked bottom-up). No matter the value of top_down, the list of subdirectories is retrieved before the triples for the directory and its subdirectories are walked.

  When top_down is true, the caller can modify the dirnames list in-place (for example, using `del` or slice assignment), and `Path.walk()` will only recurse into the subdirectories whose names remain in dirnames. This can be used to prune the search, or to impose a specific order of visiting, or even to inform `Path.walk()` about directories the caller creates or renames before it resumes `Path.walk()` again. Modifying dirnames when top_down is false has no effect on the behavior of `Path.walk()` since the directories in dirnames have already been generated by the time dirnames is yielded to the caller.

  By default, errors from `os.scandir()` are ignored. If the optional argument on_error is specified, it should be a callable; it will be called with one argument, an `OSError` instance. The callable can handle the error to continue the walk or re-raise it to stop the walk. Note that the filename is available as the `filename` attribute of the exception object.

  By default, `Path.walk()` does not follow symbolic links, and instead adds them to the filenames list. Set follow_symlinks to true to resolve symlinks and place them in dirnames and filenames as appropriate for their targets, and consequently visit directories pointed to by symlinks (where supported).

  Note

  Be aware that setting follow_symlinks to true can lead to infinite recursion if a link points to a parent directory of itself. `Path.walk()` does not keep track of the directories it has already visited.

  Note

  `Path.walk()` assumes the directories it walks are not modified during execution. For example, if a directory from dirnames has been replaced with a symlink and follow_symlinks is false, `Path.walk()` will still try to descend into it. To prevent such behavior, remove directories from dirnames as appropriate.

  Note

  Unlike `os.walk()`, `Path.walk()` lists symlinks to directories in filenames if follow_symlinks is false.

  This example displays the number of bytes used by all files in each directory, while ignoring `__pycache__` directories:

      from pathlib import Path
      for root, dirs, files in Path("cpython/Lib/concurrent").walk(on_error=print):
        print(
            root,
            "consumes",
            sum((root / file).stat().st_size for file in files),
            "bytes in",
            len(files),
            "non-directory files"
        )
        if '__pycache__' in dirs:
              dirs.remove('__pycache__')

  This next example is a simple implementation of `shutil.rmtree()`. Walking the tree bottom-up is essential as `rmdir()` doesn’t allow deleting a directory before it is empty:

      # Delete everything reachable from the directory "top".
      # CAUTION:  This is dangerous! For example, if top == Path('/'),
      # it could delete all of your files.
      for root, dirs, files in top.walk(top_down=False):
          for name in files:
              (root / name).unlink()
          for name in dirs:
              (root / name).rmdir()

  Added in version 3.12.

### Creating files and directories

Path.touch(mode=0o666, exist_ok=True)

  Create a file at this given path. If mode is given, it is combined with the process’s `umask` value to determine the file mode and access flags. If the file already exists, the function succeeds when exist_ok is true (and its modification time is updated to the current time), otherwise `FileExistsError` is raised.

  See also

  The `open()`, `write_text()` and `write_bytes()` methods are often used to create files.

Path.mkdir(mode=0o777, parents=False, exist_ok=False)

  Create a new directory at this given path. If mode is given, it is combined with the process’s `umask` value to determine the file mode and access flags. If the path already exists, `FileExistsError` is raised.

  If parents is true, any missing parents of this path are created as needed; they are created with the default permissions without taking mode into account (mimicking the POSIX `mkdir -p` command).

  If parents is false (the default), a missing parent raises `FileNotFoundError`.

  If exist_ok is false (the default), `FileExistsError` is raised if the target directory already exists.

  If exist_ok is true, `FileExistsError` will not be raised unless the given path already exists in the file system and is not a directory (same behavior as the POSIX `mkdir -p` command).

  Changed in version 3.5: The exist_ok parameter was added.

Path.symlink_to(target, target_is_directory=False)

  Make this path a symbolic link pointing to target.

  On Windows, a symlink represents either a file or a directory, and does not morph to the target dynamically. If the target is present, the type of the symlink will be created to match. Otherwise, the symlink will be created as a directory if target_is_directory is true or a file symlink (the default) otherwise. On non-Windows platforms, target_is_directory is ignored.

      >>> p = Path('mylink')
      >>> p.symlink_to('setup.py')
      >>> p.resolve()
      PosixPath('/home/antoine/pathlib/setup.py')
      >>> p.stat().st_size
      956
      >>> p.lstat().st_size
      8

  Note

  The order of arguments (link, target) is the reverse of `os.symlink()`’s.

  Changed in version 3.13: Raises `UnsupportedOperation` if `os.symlink()` is not available. In previous versions, `NotImplementedError` was raised.

Path.hardlink_to(target)

  Make this path a hard link to the same file as target.

  Note

  The order of arguments (link, target) is the reverse of `os.link()`’s.

  Added in version 3.10.

  Changed in version 3.13: Raises `UnsupportedOperation` if `os.link()` is not available. In previous versions, `NotImplementedError` was raised.

### Renaming and deleting

Path.rename(target)

  Rename this file or directory to the given target, and return a new `Path` instance pointing to target. On Unix, if target exists and is a file, it will be replaced silently if the user has permission. On Windows, if target exists, `FileExistsError` will be raised. target can be either a string or another path object:

      >>> p = Path('foo')
      >>> p.open('w').write('some text')
      9
      >>> target = Path('bar')
      >>> p.rename(target)
      PosixPath('bar')
      >>> target.open().read()
      'some text'

  The target path may be absolute or relative. Relative paths are interpreted relative to the current working directory, not the directory of the `Path` object.

  It is implemented in terms of `os.rename()` and gives the same guarantees.

  Changed in version 3.8: Added return value, return the new `Path` instance.

Path.replace(target)

  Rename this file or directory to the given target, and return a new `Path` instance pointing to target. If target points to an existing file or empty directory, it will be unconditionally replaced.

  The target path may be absolute or relative. Relative paths are interpreted relative to the current working directory, not the directory of the `Path` object.

  Changed in version 3.8: Added return value, return the new `Path` instance.

Path.unlink(missing_ok=False)

  Remove this file or symbolic link. If the path points to a directory, use `Path.rmdir()` instead.

  If missing_ok is false (the default), `FileNotFoundError` is raised if the path does not exist.

  If missing_ok is true, `FileNotFoundError` exceptions will be ignored (same behavior as the POSIX `rm -f` command).

  Changed in version 3.8: The missing_ok parameter was added.

Path.rmdir()

  Remove this directory. The directory must be empty.

### Permissions and ownership

Path.owner(*, follow_symlinks=True)

  Return the name of the user owning the file. `KeyError` is raised if the file’s user identifier (UID) isn’t found in the system database.

  This method normally follows symlinks; to get the owner of the symlink, add the argument `follow_symlinks=False`.

  Changed in version 3.13: Raises `UnsupportedOperation` if the `pwd` module is not available. In earlier versions, `NotImplementedError` was raised.

  Changed in version 3.13: The follow_symlinks parameter was added.

Path.group(*, follow_symlinks=True)

  Return the name of the group owning the file. `KeyError` is raised if the file’s group identifier (GID) isn’t found in the system database.

  This method normally follows symlinks; to get the group of the symlink, add the argument `follow_symlinks=False`.

  Changed in version 3.13: Raises `UnsupportedOperation` if the `grp` module is not available. In earlier versions, `NotImplementedError` was raised.

  Changed in version 3.13: The follow_symlinks parameter was added.

Path.chmod(mode, *, follow_symlinks=True)

  Change the file mode and permissions, like `os.chmod()`.

  This method normally follows symlinks. Some Unix flavours support changing permissions on the symlink itself; on these platforms you may add the argument `follow_symlinks=False`, or use `lchmod()`.

      >>> p = Path('setup.py')
      >>> p.stat().st_mode
      33277
      >>> p.chmod(0o444)
      >>> p.stat().st_mode
      33060

  Changed in version 3.10: The follow_symlinks parameter was added.

Path.lchmod(mode)

  Like `Path.chmod()` but, if the path points to a symbolic link, the symbolic link’s mode is changed rather than its target’s.

## Pattern language

The following wildcards are supported in patterns for `full_match()`, `glob()` and `rglob()`:

`**` (entire segment)

  Matches any number of file or directory segments, including zero.

`*` (entire segment)

  Matches one file or directory segment.

`*` (part of a segment)

  Matches any number of non-separator characters, including zero.

`?`

  Matches one non-separator character.

`[seq]`

  Matches one character in seq.

`[!seq]`

  Matches one character not in seq.

For a literal match, wrap the meta-characters in brackets. For example, `"[?]"` matches the character `"?"`.

The “`**`” wildcard enables recursive globbing. A few examples:

Pattern | Meaning
--- | ---
“`**/*`” | Any path with at least one segment.
“`**/*.py`” | Any path with a final segment ending “`.py`”.
“`assets/**`” | Any path starting with “`assets/`”.
“`assets/**/*`” | Any path starting with “`assets/`”, excluding “`assets/`” itself.

Note

Globbing with the “`**`” wildcard visits every directory in the tree. Large directory trees may take a long time to search.

Changed in version 3.13: Globbing with a pattern that ends with “`**`” returns both files and directories. In previous versions, only directories were returned.

In `Path.glob()` and `rglob()`, a trailing slash may be added to the pattern to match only directories.

Changed in version 3.11: Globbing with a pattern that ends with a pathname components separator (`sep` or `altsep`) returns only directories.

## Comparison to the `glob` module

The patterns accepted and results generated by `Path.glob()` and `Path.rglob()` differ slightly from those by the `glob` module:

1. Files beginning with a dot are not special in pathlib. This is like passing `include_hidden=True` to `glob.glob()`.

2. “`**`” pattern components are always recursive in pathlib. This is like passing `recursive=True` to `glob.glob()`.

3. “`**`” pattern components do not follow symlinks by default in pathlib. This behaviour has no equivalent in `glob.glob()`, but you can pass `recurse_symlinks=True` to `Path.glob()` for compatible behaviour.

4. Like all `PurePath` and `Path` objects, the values returned from `Path.glob()` and `Path.rglob()` don’t include trailing slashes.

5. The values returned from pathlib’s `path.glob()` and `path.rglob()` include the path as a prefix, unlike the results of `glob.glob(root_dir=path)`.

6. The values returned from pathlib’s `path.glob()` and `path.rglob()` may include path itself, for example when globbing “`**`”, whereas the results of `glob.glob(root_dir=path)` never include an empty string that would correspond to path.

## Comparison to the `os` and `os.path` modules

pathlib implements path operations using `PurePath` and `Path` objects, and so it’s said to be object-oriented. On the other hand, the `os` and `os.path` modules supply functions that work with low-level `str` and `bytes` objects, which is a more procedural approach. Some users consider the object-oriented style to be more readable.

Many functions in `os` and `os.path` support `bytes` paths and paths relative to directory descriptors. These features aren’t available in pathlib.

Python’s `str` and `bytes` types, and portions of the `os` and `os.path` modules, are written in C and are very speedy. pathlib is written in pure Python and is often slower, but rarely slow enough to matter.

pathlib’s path normalization is slightly more opinionated and consistent than `os.path`. For example, whereas `os.path.abspath()` eliminates “`..`” segments from a path, which may change its meaning if symlinks are involved, `Path.absolute()` preserves these segments for greater safety.

pathlib’s path normalization may render it unsuitable for some applications:

1. pathlib normalizes `Path("my_folder/")` to `Path("my_folder")`, which changes a path’s meaning when supplied to various operating system APIs and command-line utilities. Specifically, the absence of a trailing separator may allow the path to be resolved as either a file or directory, rather than a directory only.

2. pathlib normalizes `Path("./my_program")` to `Path("my_program")`, which changes a path’s meaning when used as an executable search path, such as in a shell or when spawning a child process. Specifically, the absence of a separator in the path may force it to be looked up in `PATH` rather than the current directory.

As a consequence of these differences, pathlib is not a drop-in replacement for `os.path`.

Footnotes

[1]

`os.path.relpath()` calls `abspath()` to make paths absolute and remove “`..`” parts, whereas `PurePath.relative_to()` is a lexical operation that raises `ValueError` when its inputs’ anchors differ (e.g. if one path is absolute and the other relative.)

[2]

`os.path.expanduser()` returns the path unchanged if the home directory can’t be resolved, whereas `Path.expanduser()` raises `RuntimeError`.

[3]

`os.path.abspath()` removes “`..`” components without resolving symlinks, which may change the meaning of the path, whereas `Path.absolute()` leaves any “`..`” components in the path.

[4]

`os.walk()` always follows symlinks when categorizing paths into dirnames and filenames, whereas `Path.walk()` categorizes all symlinks into filenames when follow_symlinks is false (the default.)
