For Python 3.4+, you should use pathlib.PurePath.relative_to. From the documentation:

>>> p = PurePosixPath('/etc/passwd')
>>> p.relative_to('/')
PurePosixPath('etc/passwd')

>>> p.relative_to('/etc')
PurePosixPath('passwd')

>>> p.relative_to('/usr')
Traceback (most recent call last):
  File "", line 1, in 
  File "pathlib.py", line 694, in relative_to
    .format(str(self), str(formatted)))
ValueError: '/etc/passwd' does not start with '/usr'
