Work with the pillars of OOP in Python, including classes, inheritance, and polymorphism.

Python for Programmers

In this module, we’ll learn to write cleaner, more modular, and more scalable code in Python by gaining mastery in object-oriented programming (OOP). We'll start with the basics of object-oriented programming and move to more advanced concepts such as inheritance, information hiding, and polymorphism. Along the way, we'll learn how each concept applies to Python in particular, as well as how various Python features make it particularly convenient for OOP. This module has hands-on coding challenges, playgrounds, snippets, and illustrations to keep things interactive.
