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. Mac, Windows), os.path provides the same operations in a manner specific to that platform, and is an alias to another module (e.g. macpath, ntpath). Some of this can actually be useful on non-Posix systems too, e.g. for manipulation of the pathname component of URLs. �.z..�/�:z:/bin:/usr/binNz /dev/null� )�*�normcase�isabs�join� splitdrive�split�splitext�basename�dirname� commonprefix�getsize�getmtime�getatime�getctime�islink�exists�lexists�isdir�isfile�ismount� expanduser� expandvars�normpath�abspath�samefile� sameopenfile�samestat�curdir�pardir�sep�pathsep�defpath�altsep�extsep�devnull�realpath�supports_unicode_filenames�relpath� commonpath� ALLOW_MISSINGc C s t | t�rdS dS d S )N� /r )� isinstance�bytes)�path� r1 �!/usr/lib64/python3.6/posixpath.py�_get_sep) s r3 c C s. t j| �} t| ttf�s*tdj| jj���| S )z6Normalize case of pathname.
