You can find my talk as a Jupyter Notebook located here:

https://github.com/swyatt7/CC_ObjectOriented

It overviews the 4 pillars of Object Oriented Programming (OOP) then provides a basic tutorial on how to implement classes in Python. There are also some astronomical examples followed by some cool OOP aspects in Python.
