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. r8r7rDrrrErrFNrA)r9r:rCr0r1r;find)rPr!r$rOZnormpindexZindex2r4r4r5r |s.   $  cCsxt|}t|}t|\}}t|}|rD||d|krD|d8}q&|d|||d}}||pj|}|||fS)z~Split a pathname.
