In this video we overview the main things I think are pointing when you are starting to learn about classes & integrate them in your everyday code. In this video we cover:
why should we use object oriented programming (oop) ?
the basics of defining a class in python (__init__)
class methods
what the heck is "self"?
Inheritance & Subclassing
Operator overriding

A timeline is in the comments.

If there are topics you felt like I left out, let me know in the comments! I'll potentially make a follow up video to this one.

For an example of me structuring my code with classes, check out this machine learning video:   • Real-World Python Machine Learning Tu...  

If you want to practice using classes, try rewriting the game we build in this video to use them:   • How to Program a Game! (in Python)  

^(I'll update the github repo for that video with my solution to this soon)
