Python Basics: Object-Oriented Programming

OOP, or object-oriented programming, is a method of structuring a program by bundling related properties and behaviors into individual objects. Conceptually, objects are like the components of a system. Think of a program as a factory assembly line of sorts. At each step of the assembly line, a system component processes some material, ultimately...
