Summary

object_oriented_programming organizes code into class blueprints and object instances. A class defines attribute data and method behavior. A constructor creates an object. Core ideas: encapsulation hides data behind methods, inheritance lets a class reuse another, polymorphism lets one interface call different implementations, and abstraction focuses on essentials. Remember message_passing: objects call each other’s methods. Common benefits: modular code, reuse, and models that map to real entities.
