A Deep Dive into Python's Dataclasses (Part 2)
This is Part 2 of a two-part set of videos that takes a deep dive into Python dataclasses.
The goal of these videos is not to learn just the mechanics of defining classes using dataclasses, but rather to understand how dataclasses add functionality to classes, and understand the equivalent code we would have to write using regular classes. Understanding dataclasses at this fundamental level will help you understand why certain things may or may not work in your own dataclasses and how to solve your issues.
So, don't expect a 10-minute run down of how to create dataclasses!!
