Summary

A class is a blueprint for objects. It groups attributes and methods. A class_definition names the class_name and declares members. A constructor initializes a new instance. Use this_keyword or self_keyword to refer to the current object. encapsulation hides data with access_modifiers. inheritance lets a class extend a base_class. polymorphism lets methods share a name with different behavior. class_methods belong to the class, and instance_methods belong to each object. Create objects with instantiation.
