How do I case fold a string in Python 2?

Question

Python 3.3 adds the casefold method to the str type, but in 2.x I don\'t have anything. What\'s the best way to work around this?

Answer 1

Check out py2casefold.

>>> from py2casefold import casefold
>>> print casefold(u"tschüß")
tschüss
>>> casefold(u"ΣίσυφοςfiÆ") == casefold(u"ΣΊΣΥΦΟσFIæ") == u"σίσυφοσfiæ"
True
