Why do Python projects turn into spaghetti so easily? In this video, I show how using abstraction (with Callable, ABC, and Protocol) can dramatically clean up your code. We’ll take a simple image processing example and refactor it step by step, making it more flexible, testable, and maintainable. Even small projects benefit from the right abstractions early on.
