Python?

I have just found out about Breve and would like to do some artificial evolution stuff with it. I'm an experienced Python programmer, so that's the direction I'd like to take.

How well supported is Python right now? I've been playing with the Creatures.(tz|py) files but am having problems with the python version. The creatures just pile up on top of each other and the simulation doesn't proceed past the first generation. I've tried making modifications to the Creatures.py file but am getting errors that I would never expect to see in an ordinary Python interpreter. For example, adding a line of code to reference an object fails even though that very object is referenced (successfully) in the very next line of original Python code.

Generally, would it make sense to try to dive in and work with Breve via Python code at this point? Is it even still a viable project?
