Help on module posixpath:

## NAME
    posixpath - Common operations on Posix pathnames.

## MODULE REFERENCE
    <https://docs.python.org/3.10/library/posixpath.html>

    The following documentation is automatically generated from the Python
    source files.  It may be incomplete, incorrect or include features that
    are considered implementation detail and may vary between Python
    implementations.  When in doubt, consult the module reference at the
    location listed above.

## DESCRIPTION
    Instead of importing this module directly, import os and refer to
    this module as os.path.  The "os.path" name is an alias for this
    module on Posix systems; on other systems (e.g. Windows),
    os.path provides the same operations in a manner specific to that
    platform, and is an alias to another module (e.g. ntpath).

    Some of this can actually be useful on non-Posix systems too, e.g.
    for manipulation of the pathname component of URLs.

## FUNCTIONS
### abspath
        Return an absolute path.

### basename
        Returns the final component of a pathname

### commonpath
        Given a sequence of path names, returns the longest common sub-path.

### commonprefix
        Given a list of pathnames, returns the longest common leading component

### dirname
        Returns the directory component of a pathname

### exists
        Test whether a path exists.  Returns False for broken symbolic links

### expanduser
        Expand ~ and ~user constructions.  If user or $HOME is unknown,
        do nothing.

### expandvars
        Expand shell variables of form $var and ${var}.  Unknown variables
        are left unchanged.

### getatime
        Return the last access time of a file, reported by os.stat().

### getctime
        Return the metadata change time of a file, reported by os.stat().

### getmtime
        Return the last modification time of a file, reported by os.stat().

### getsize
        Return the size of a file, reported by os.stat().

### isabs
        Test whether a path is absolute

### isdir
        Return true if the pathname refers to an existing directory.

### isfile
        Test whether a path is a regular file

### islink
        Test whether a path is a symbolic link

### ismount
        Test whether a path is a mount point

### join
        Join two or more pathname components, inserting '/' as needed.
        If any component is an absolute path, all previous path components
        will be discarded.  An empty last part will result in a path that
        ends with a separator.

### lexists
        Test whether a path exists.  Returns True for broken symbolic links

### normcase
        Normalize case of pathname.  Has no effect under Posix

### normpath
        Normalize path, eliminating double slashes, etc.

### realpath
        Return the canonical path of the specified filename, eliminating any
        symbolic links encountered in the path.

### relpath
        Return a relative version of a path

### samefile
        Test whether two pathnames reference the same actual file or directory

        This is determined by the device number and i-node number and
        raises an exception if an os.stat() call on either pathname fails.

### sameopenfile
        Test whether two open file objects reference the same file

### samestat
        Test whether two stat buffers reference the same file

### split
        Split a pathname.  Returns tuple "(head, tail)" where "tail" is
        everything after the final slash.  Either part may be empty.

### splitdrive
        Split a pathname into drive and path. On Posix, drive is always
        empty.

### splitext
        Split the extension from a pathname.

        Extension is everything from the last dot to the end, ignoring
        leading dots.  Returns "(root, ext)"; ext may be empty.
