simplegeo's python-oauth2. The Python OAuth library scene is frighteningly complicated at the moment. This seems to be the most actively maintained, and the readme includes working example code for talking to the Twitter API (including integration with Django auth).
I used it recently and its really good.

Since Facebook supports OAuth 2.0 now (and since their Python SDK sucks), I went ahead and added an OAuth 2.0 client class to a fork of simplegeo's oauth library: http://github.com/dgouldin/python-oauth2
It makes a couple of assumptions about how it's used and I've only used it with Facebook so far (any other OAuth 2.0 services out there to test on?), but it seems passable.
