Put:
# -*- coding: UTF-8 -*-
as the first line of the file (or second line if using *nix) and save the file as UTF-8.
If you're using Python 2, use Unicode string literals (u"..."), for example:
means = u"a ، b ، c"
lst = means.split(u"،")
If you're using Python 3, string literals are Unicode already (unless marked as bytestrings b"...").
