I have a program that should be runnable on windows and linux systems. One function I use cuts off some root of a path and leaves me with the relative path.

import re
from pathlib import Path
def relative_path(absolute_absolute, root_path):
    a = str(absolute_absolute)
    r = str(root_path)
    assert re.search(r, a) is not None, (r, a)
    return Path(a.replace(r, './'))

It works under Linux, but under windows I get

incomplete escape \U

The windows path looks like C:\Users\....

What is the best way to deal with this? Is it OK to replace \ with \\?

Yes, you need to escape the backslashes. – pavi2410 Nov 09 '18 at 18:13
Closing as related (enough) to the duplicate question. There are two actual approaches. Either escape the backslashes, or use raw strings. – g.d.d.c Nov 09 '18 at 18:50
