This repository contains the code for the Composition vs inheritance video on the ArjanCodes channel (watch the video here).
The example is about different employee types and reward structures. In the first version (before.py), there is no inheritance, just three classes (= three employee types) with low cohesion (lots of responsibilities per class), and code duplication. Then there is a version that tries to solve those issues with inheritance (with_inheritance.py), and another version that uses composition (with_composition.py).
