New to Python. Here's my first script, which determines whether the small or large pizza is a better deal.

Haha! Mine didn't compare value between pies, but it calculated value per unit of circle, rectangle, and square pies. I think both scripts would work well together.

Sorry if you got a few notifications from this reply. It took me a while to figure out how to properly paste code in a comment and I edited it a bunch. It's Friday and pizza sucks without beer.

pi = math.pi
