Banana-py
A simple OAuth2 library for Django and MailChimp users.
Banana-Py is the little library that we wrote for MailChimp to provide a simple library for using their OAuth2 authentication with Django. It doesn’t automatically create a user for you like some social apps do, but it provides all of the user’s details in request.session.mailchimp_details so you can do what you want with them afterwards.
You can check out the project on Github or install it straight off PyPI with pip install banana-py. There are also some simple slides we created for announcing the project at DjangoCon 2011 here.
