Python supports
object-oriented programming (OOP) using the built-in class
keyword. OOP allows advanced programming techniques and sustainable code that supports better software development. Because OOP is not commonly used in scripting and is above the introductory level, this book will implement OOP and some of its features in later chapters after we master the basic features of Python. Everything in Python, including classes, functions, and variable, are objects. Classes are useful in a variety of situations, allowing us to design our own objects to interact with data in a custom manner.
