Summary
Metaprogramming is a valuable technique for putting complexity where it belongs: behind a clean, friendly API. This talk goes over the basics of metaclasses and introspection in Python, and covers how and when you should use them to make your code more approachable.

Abstract
Python's Metaclasses are an "advanced" technique, but once you get started they're surprisingly approachable.
Starting with the basics, we'll:
- figure out what a metaclass does
- point out some existing metaclasses you might already have used
- see where you might use one in your own code.
We'll compare use of a metaclass with some alternatives that don't use metaclasses, to better understand why you'd want to use them.
Then we'll take a look at a couple of use-cases where using a metaclass helps us achieve a much more friendly and intuitive API than we otherwise could.
