Realistically a Python coder with a little experience will have a glance at 
your code and run away.

But: a family member, or friend, or even you yourself with a small real-
world problem will not care whether your code is idiomatic Python as long as 
it works as advertised. So I'd look that way.

As you idle along you'll quickly get better and may encounter a library 
where you think "That might be a useful extension" or one where you think 
"That's much too complex, I can make it simpler for 80% of the use cases". 

Voilà your contributions to the community.


PS: Regarding your MovingAverage class, have a look at zip(), generators or 
the __iter__() method, and -- most important -- unit tests.
