Hi,
I'm trying to implement a function which returns whether a path is a
subpath of another one (e.g. /a/b/c is a subpath of /a/b).
I wrote this function which apparently seems to work fine:

import os

def issubpath(path1, path2):
    """Return True if path1 is a sub path of path2."""
    if path1 == path2:
        return False
    x1 = path1.split(os.sep)
    x2 = path2.split(os.sep)
    return x1[:len(x2)] == x2

...but if I use "issubpath('C:\\dir', 'C:\\')" it returns False.
A little help would be appreciated.

Any reason why

os.path.normpath(a).startswith(os.normpath(b)) doesn't do the trick?
