# `pathlib` — Object-oriented filesystem paths

Nou în versiunea 3.4.

Source code: Lib/pathlib.py

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'

## 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, an object implementing the `os.PathLike` interface which returns a string, or 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.

  Schimbat în versiunea 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')
      PurePosixPath('/etc')

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

Notă

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.``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
      '/'

  Notă

  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:/')

  Schimbat în versiunea 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('.')

  Notă

  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 file extension of the final component, if any:

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

`PurePath.``suffixes`

  A list of the path’s 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.``as_uri`()

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

      >>> p = PurePosixPath('/etc/passwd')
      >>> p.as_uri()
      'file:///etc/passwd'
      >>> p = PureWindowsPath('c:/Windows')
      >>> p.as_uri()
      'file:///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

  Nou în versiunea 3.9.

`PurePath.``is_reserved`()

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

      >>> PureWindowsPath('nul').is_reserved()
      True
      >>> PurePosixPath('nul').is_reserved()
      False

  File system calls on reserved paths can fail mysteriously or have unintended effects.

`PurePath.``joinpath`(*other)

  Calling this method is equivalent to combining the path with each of the other arguments 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.``match`(pattern)

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

  If pattern is relative, the path can be either relative or absolute, and 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

  If pattern is absolute, the path must be absolute, and the whole path must match:

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

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

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

`PurePath.``relative_to`(*other)

  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 694, in relative_to
          .format(str(self), str(formatted)))
      ValueError: '/etc/passwd' is not in the subpath of '/usr' OR one path is relative and the other absolute.

  NOTE: This function is part of `PurePath` and works with strings. It does not check or access the underlying file structure.

`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

  Nou în versiunea 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')

## 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')
      PosixPath('/etc')

  pathsegments is specified similarly to `PurePath`.

class `pathlib.``WindowsPath`(*pathsegments)

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

      >>> WindowsPath('c:/Program Files/')
      WindowsPath('c:/Program Files')

  pathsegments is specified similarly to `PurePath`.

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__,))
    NotImplementedError: cannot instantiate 'WindowsPath' on your system

### Methods

Concrete paths provide the following methods in addition to pure paths methods. Many of these methods can raise an `OSError` if a system call fails (for example because the path doesn’t exist).

Schimbat în versiunea 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.

classmethod `Path.``cwd`()

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

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

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')

  Nou în versiunea 3.5.

`Path.``stat`(*, follow_symlinks=True)

  Return a `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

  Schimbat în versiunea 3.10: 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

  Schimbat în versiunea 3.10: The follow_symlinks parameter was added.

`Path.``exists`()

  Whether the path points to an existing file or directory:

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

  Notă

  If the path points to a symlink, `exists()` returns whether the symlink points to an existing file or directory.

`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')

  Nou în versiunea 3.5.

`Path.``glob`(pattern)

  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')]

  Patterns are the same as for `fnmatch`, with the addition of „`**`” which means „this directory and all subdirectories, recursively”. In other words, it enables recursive globbing:

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

  Notă

  Using the „`**`” pattern in large directory trees may consume an inordinate amount of time.

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

`Path.``group`()

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

`Path.``is_dir`()

  Return `True` if the path points to a directory (or a symbolic link pointing 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.

`Path.``is_file`()

  Return `True` if the path points to a regular file (or a symbolic link pointing 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.

`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. Not implemented on Windows.

  Nou în versiunea 3.7.

`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_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.``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, whether a path object for that file be included is unspecified.

`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.

`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.``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» `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` exceptions will be ignored (same behavior as the POSIX `mkdir -p` command), but only if the last path component is not an existing non-directory file.

  Schimbat în versiunea 3.5: The exist_ok parameter was added.

`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.``owner`()

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

`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'

  Nou în versiunea 3.5.

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

  Nou în versiunea 3.5.

`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')

  Nou în versiunea 3.9.

`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.

  Schimbat în versiunea 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.

  Schimbat în versiunea 3.8: Added return value, return the new Path instance.

`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 the path doesn’t exist and strict is `True`, `FileNotFoundError` is raised. If strict is `False`, the path is resolved as far as possible and any remainder is appended without checking whether it exists. If an infinite loop is encountered along the resolution path, `RuntimeError` is raised.

  Nou în versiunea 3.6: The strict argument (pre-3.6 behavior is strict).

`Path.``rglob`(pattern)

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

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

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

`Path.``rmdir`()

  Remove this directory. The directory must be empty.

`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

  Nou în versiunea 3.5.

`Path.``symlink_to`(target, target_is_directory=False)

  Make this path a symbolic link to target. Under Windows, target_is_directory must be true (default `False`) if the link’s target is a directory. Under POSIX, target_is_directory’s value 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

  Notă

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

`Path.``hardlink_to`(target)

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

  Notă

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

  Nou în versiunea 3.10.

`Path.``link_to`(target)

  Make target a hard link to this path.

  Atenționare

  This function does not make this path a hard link to target, despite the implication of the function and argument names. The argument order (target, link) is the reverse of `Path.symlink_to()` and `Path.hardlink_to()`, but matches that of `os.link()`.

  Nou în versiunea 3.8.

  Învechit începând cu versiunea 3.10: This method is deprecated in favor of `Path.hardlink_to()`, as the argument order of `Path.link_to()` does not match that of `Path.symlink_to()`.

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

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

`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).

  Schimbat în versiunea 3.8: The missing_ok 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.

  Nou în versiunea 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()`.

Footnotes

1

  `os.path.abspath()` does not resolve symbolic links while `Path.resolve()` does.

2

  `PurePath.relative_to()` requires `self` to be the subpath of the argument, but `os.path.relpath()` does not.
