[Chicago] Just sharing with everyone in the group.

Spaces and tabs both work, but if you mix them it creates a terrible mess.
So by convention, we all agreed to use spaces for our collective sanity.


I wanted to make another very slight criticism of your code; often when
people start learning Python they get to the part about classes and
inheritance and start using classes for everything.  So it's good to see
that you've figured out how that works, but it's not really helpful to your
program.  I can see ways that all could be much simpler!


Well done though, and thank you for posting actual Python code :)
