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:https://youtu.be/M9Itm95JzL0
If you want to practice using classes, try rewriting the game we build in this video to use them:https://youtu.be/-8n91btt5d8
^(I'll update the github repo for that video with my solution to this soon)
