For a head start take a look here: http://pylonshq.com/project/pylons/browser/RailsHelpers
Pylons being an in-development python "mega" framework (not a fan of that term!). I don't know anything of licensing or credit issues, but they're ported from Rails, so... maybe ask Ben over there, he did the work I believe. You'd need to Django-ize them but it should still be a big help...
