Returns a 2-tuple (drive_or_unc, path); either part may be empty. If you assign result = splitdrive(p) It is always true that: result[0] + result[1] == p If the path contained a drive letter, drive_or_unc will contain everything up to and including the colon. e.g. splitdrive("c:/dir") returns ("c:", "/dir") If the path contained a UNC path, the drive_or_unc will contain the host name and share up to but not including the fourth directory separator character. e.g. splitdrive("//host/computer/dir") returns ("//host/computer", "/dir") Paths cannot contain both a drive letter and a UNC path. i i i i i����R/ R0 ( t lenR, R R t find( R5 t normpt indext index2( ( s /usr/lib/python2.7/ntpath.pyR ` s * c C s� | d d !d k r d | f S| d d !} | d k sB | d k r� | j d d � } | j d d � } | d k r| d | f S| j d | d � } | | d k r� d | f S| d k r� t | � } n | | | | f Sd | f S( s? Split a pathname into UNC mount point and relative path specifiers. Return a 2-tuple (unc, rest); either part may be empty.

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 warnpy3kt ost listdirt errorR R R ( t topt funct argt namest name( ( s /usr/lib/python2.7/ntpath.pyR � s c C s | d d k r | Sd t | � } } x* | | k rS | | d k rS | d } q* Wd t j k rs t j d } ns d t j k r� t j d } nT d t j k r� | Sy t j d } Wn t k r� d } n Xt | t j d � } | d k rt t | � | d | !� } n | | | S( sL Expand ~ and ~user constructs.
