"pathlib" --- Object-oriented filesystem paths
**********************************************

3.4 sürümünde geldi.

**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.

[resim]

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.

   3.6 sürümünde değişti: 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'

Not:

  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
      '/'

   Not:

     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:/')

   3.10 sürümünde değişti: 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('.')

   Not:

     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

   3.9 sürümünde geldi.

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

   3.9 sürümünde geldi.

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).

3.8 sürümünde değişti: "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')

   3.5 sürümünde geldi.

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

   3.10 sürümünde değişti: 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

   3.10 sürümünde değişti: 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

   Not:

     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')

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')]

   Not:

     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.

   3.7 sürümünde geldi.

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.

   3.5 sürümünde değişti: 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'

   3.5 sürümünde geldi.

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()".

   3.5 sürümünde geldi.

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')

   3.9 sürümünde geldi.

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.

   3.8 sürümünde değişti: 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.

   3.8 sürümünde değişti: 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.

   3.6 sürümünde geldi: 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

   3.5 sürümünde geldi.

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

   Not:

     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*.

   Not:

     The order of arguments (link, target) is the reverse of
     "os.link()"'s.

   3.10 sürümünde geldi.

Path.link_to(target)

   Make *target* a hard link to this path.

   Uyarı:

     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()".

   3.8 sürümünde geldi.

   3.10 sürümünden beri kullanım dışı: 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).

   3.8 sürümünde değişti: 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.

   3.5 sürümünde geldi.

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()".

   3.5 sürümünde geldi.

   3.10 sürümünde değişti: The *newline* parameter was added.

-[ 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.
