与os.path.commonprefix相反

Question

os.path.commonprefix的反义词是什么？我有两条路径,我想要非重叠路径,例如:

>>> p1 = '/Users/foo/something'
>>> p2 = '/Users/foo/something/else/etc'
>>> print somefunction([p1, p2])
'/else/etc'

Answer 1

>>> p1 = '/Users/foo/something'
>>> p2 = '/Users/foo/something/else/etc'
>>> os.path.relpath(p2, start=p1)
'else/etc'

正确的答案是'else/etc'不'/else/etc'.

如果你在p1和键入cd /else/etc你不会降落在p2,而是在其他地方.

os.path.join(p1, 'else/etc') 再次给你p2.
