Thanks for all the remarks, I'll restructure my code. Probably the 
biggest mistake was not keeping "moving average" class and others 
focused on its respective jobs only.

However, unit tests are a tougher cookie, do you have any resource 
that's truly worth recommending for learning unit tests? The only 
resource I found that was talking at some length about it was "Dive into 
Python" and I was wondering if there's anything better out there...
