Inheritance
Making a new class from an existing one, so it gets the parent's attributes and methods and changes only what differs; and knowing when to hold another object instead.
Depth 1 · Foundation
You can write a subclass that inherits its parent's methods, overrides some, and calls the parent's with `super()`; you know how Python looks a method up, and you choose composition when one thing *has* another rather than *is* one.
