What other languages do with interfaces, Python does with duck-typing. You
can build something like interfaces in Python, but many people don't bother.

I don't know if your project will be web-based, but here is an entire book
about developing Python web sites with a TDD approach:

http://www.obeythetestinggoat.com/

(Don't mind the unusual domain name, it's a bit of an inside joke...)

TDD and interfaces are separate concepts, and I'm not sure they even
intersect.  TDD is about writing tests as a way to design the best system,
and putting testing at the center of your development workflow.  It works
great with Python even without interfaces.
