Python Medium Theory

Instance methods, class methods, static methods, `@property`, setters, deleters, and dataclasses

Instance methods work with object state, class methods work with the class, static methods are utility functions inside the namespace, properties expose attribute-style access, and dataclasses reduce boilerplate.

Choose method type based on state access
Properties can validate or compute values
Dataclasses generate common methods automatically
