Question

PYTHON: please add 2 more classes and 2 more methods to each of those classes that relates to the game. As long as it relates to the game the 2 classses and 4 methods can be anything.

class MathZombie:
    left = 0

Explanation / Answer

To solve this issue, you break up pieces of functionality into their own classes and encapsulate all the logic. Then when you want to work on the class, you don't need to think about what else is going on in the code. You can just focus on that small piece of code. This is invaluable for working efficiently, however it's hard to appreciate without working on applications that are huge.

Of course there are countless other benefits to breaking your code into smaller pieces: the code is more maintainable, more testable, more resusable, etc., but to me the largest benefit is that it makes massive programs manageable by reducing the amount of code you need to think about at one time.

The simplest answer is that if you put everything into one class, you have to worry about everything at once when you're writing new code. This may work for small projects, but for huge applications (we're talking hundreds of thousands of lines), this quickly becomes next to impossible.
