This course introduces advanced programming skills and focuses on the core concepts of object-oriented programming (OOP) using Python, a high-level language. OOP shifts the focus from thinking about code as a sequence of actions, to looking at your program as a collection of objects that interact with each other. The course focuses on the understanding and practical mastery of object-oriented concepts such as classes, objects, data abstraction, methods, and the three tenets of OOP: encapsulation, inheritance, and polymorphism.
