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. � r5 r4 rB r r rC r � r@ NrD rD )r6 r7 rA r. r/ r8 �find)rL r! r$ rK Znormp�indexZindex2r1 r1 r2 r z s. $ c C sF ddl }|jdtd� t| �\}}t|�dkr>| dd� | fS ||fS )a� Deprecated since Python 3.1.
