If you know how to use variables in Python, this works similarly: except instead of storing one piece of data as an integer, you are storing custom information about an object you conceived.

Python classes can make your code more complicated than necessary. So when should you use classes, and when should you use standard functions instead?

Dataclasses, introduced in Python 3.7 (and backported to Python 3.6), provide a handy, less verbose way to create classes.

A Python module is an external class or set of functions that exist outside the main file of your program. This can be something that you built yourself, or it can be provided by the community.
