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. � N)�*�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�.z..�/�:z:/bin:/usr/binz /dev/nullc C s t | t � r d Sd Sd S)N� /r) )� isinstance�bytes)�path� r/ �./opt/alt/python34/lib64/python3.4/posixpath.py�_get_sep& s r1 c C s7 t | t t f � s3 t d j | j j � � � n | S)z6Normalize case of pathname.
