Python supports the object-oriented programming paradigm
The main OOP concepts:
- an object as a model of a real object
- a class as a factory for objects or as a template that defines the structure of objects from this class and behavior of objects from this class
- an object as an instance of a class
- a method with or without parameters describes the behavior of instances
- calling or invoking method

A class can only "implement" an interface. A class only "extends" a class. Likewise, an interface can extend another interface. A class can only extend one other class. A class can implement several interfaces.
Extends makes it a child, inherit the class' methods and shit. You can override its shit if you want.
Implements allows you inherit the constants that are declared, and you can define these constants. The way that works is it provides a bunch of empty methods, and you fill in the gaps
