Explore implementations of Python classes, methods, and instance and class variables in this 15-video course. Learn how to implement private variables in Python classes and program problems with classes. Key concepts covered here include how to create classes by using Python; how to assign attributes to objects of classes; and how to initialize class variables by using the init special method. Next, you will observe how to initialize values for a class when you create objects; how to pass arguments to initialize the state of a class object; and additional methods in a class, as well as how class variables work. Learners will examine how class variables are different from instance variables and how class variables share memory across objects of a class; and work with variables that have their own memory in each object. Then examine getters and setters for each instance variable; learn to prevent inadvertent modification of instance variables; and learn to create a class to represent a real-world entity. Finally, observe how to parse information to create classes with a dictionary.
