openID in wsgi with Python 3

I have never done authentication stuff before, but would like to be able to track and authenticate users via openID. I saw a couple modules that allow for openID authentication with WSGI, but all are old and none mention python3, so I'm guessing they do not work.

I'd like some suggestions as to how to handle/authenticate openID in WSGI and python3. A simple implementation would be appreciated.
