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. i����N( t *( t _unicodet normcaset isabst joint splitdrivet splitt splitextt basenamet dirnamet commonprefixt getsizet getmtimet getatimet getctimet islinkt existst lexistst isdirt isfilet ismountt walkt expandusert expandvarst normpatht abspatht samefilet sameopenfilet samestatt curdirt pardirt sept pathsept defpatht altsept extsept devnullt realpatht supports_unicode_filenamest relpatht .s ..t /t :s :/bin:/usr/bins /dev/nullc C s | S( s6 Normalize case of pathname.

For each directory in the directory tree rooted at top (including top itself, but excluding '.' and '..'), call func(arg, dirname, fnames). dirname is the name of the directory, and fnames a list of the names of the files and subdirectories in dirname (excluding '.' and '..'). func may modify the fnames list in-place (e.g. via del or slice assignment), and walk will only recurse into the subdirectories whose names remain in fnames; this can be used to implement a filter, or to impose a specific order of visiting. No semantics are defined for, or required of, arg, beyond that arg is always passed to func. It can be used, e.g., to pass a filename pattern, or a mutable object designed to accumulate statistics. Passing None for arg is common.s4 In 3.x, os.path.walk is removed in favor of os.walk.t stackleveli N( t warningst warnpy3kR; t listdirR= R R< R@ t S_ISDIRRB R ( t topt funct argt namest nameRC ( ( s. /opt/alt/python27/lib64/python2.7/posixpath.pyR � s c C s | j d � s | S| j d d � } | d k r@ t | � } n | d k r� d t j k r� d d l } y | j t j � � j } Wq� t k r� | SXq� t j d } nD d d l } y | j | d | !� } Wn t k r� | SX| j } | j d � } | | | pd S( sO Expand ~ and ~user constructions.
