The templates don't support that kind of functionality directly. You'll
probably want to create your own template tag that will do for you - you can
recurse to your heart's content in Python.

Check out the docs at
http://www.djangoproject.com/documentation/templates_python/ for a good
overview. Making one is really pretty straightfoward.
