The Strategy Pattern Will Make Your Python Code CLEANER

If we have lots of different ways of doing the same thing, how do we best represent that in Python? If we want to take a payment, but want to change our payment processor on the fly, how do we write clean, idiomatic Python code without lots of conditional statements everywhere?

First time I've heard "strategy pattern". However, I have implemented something like this many times.

Dependency Injection?
Composable Interfaces?
Traits?
Heck, even a C header declaration can do this.
