• Inheritance and Composition in Python OO
• OO-Programming – This is a chapter from a book called Beyond the Basic Stuff With Python by Al Sweigart. He has written a ton of great books on Python and makes them available to read for free online at inventwithpython.com. You might check out Automate the Boring Stuff with Python. It’s a fantastic beginner book.

Classes in Python

Useful resources for debugging

• Scope of Variables in Python
• 🐛 Debugging Python For Fun & Profit (video)
• Code Style Checks in Python We installed flake8 on the first day of this phase. This post gives you some detail about what it’s for and why you need it.
