In this course, you’ll explore inheritance and composition in Python. Inheritance and composition are two important concepts in object oriented programming that model the relationship between two classes. They are the building blocks of object oriented design, and they help programmers to write reusable code.

By the end of this course, you’ll know how to:

Use inheritance in Python
Model class hierarchies using inheritance
Use multiple inheritance in Python and understand its drawbacks
Use composition to create complex objects
Reuse existing code by applying composition
Change application behavior at run-time through composition

Thanks for a great course, Austin. I learned a ton of new stuff and have to watch at least one more time to pick up the details.

Very good course. I have already gone through twice, the second time I used the pause button frequently and also backup and went back through some sections. I am sure I will be revisiting this course as well as the tutorial. Looking forward to seeing those files for downloading. Thanks for a job well done.

Thanks for the great videos! I like that you ask us questions so we can test our understanding. This really fortifies the understanding we have, exposes gaps we may still have, and helps commit the information to memory! Keep it going :D

This is by far the best course on this subject. Excellent, needs going over and over again.

Superb course; I will be going back to this time and again. I am about a year into my Python journey and this course appeared at just the right moment.
