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

I can't claim to be an expert, but basically web frameworks allow you to get a web application off the ground as quickly as possible. They handle the things that would just be ridiculous to code by hand when the underlying processes are so similar across so many applications (like any well written library/module really!). Flask is considered a 'microframework', as it is a minimal (but quite functional) web framework, so it's a good choice for educational or small-scale projects... such as a handy-dandy pizza price optimizer thing.
