Python 3 Deep Dive — Part 4 Oop High Quality

Abstract classes and interfaces are used to define a blueprint for other classes to follow. An abstract class is a class that cannot be instantiated on its own and is meant to be inherited by other classes.

In Python 3, a class is a template that defines the properties and behavior of an object. A class is essentially a blueprint or a design pattern that defines the characteristics of an object. An object, on the other hand, is an instance of a class, which has its own set of attributes (data) and methods (functions). python 3 deep dive part 4 oop high quality
