So I have a project in Object-Oriented Programming and that is to make a Python Package (It has to be functional and not just making a python package (for example math module )) I need your help to think about the concept of my Package/ Module because I'm a bit clueless about which particular topic should I choose. If ever you had a previous project in python where is it about making a functional Package, if it's okay with you please share it with me.

Ps. If you don't have a previous project like this just give me at least 5 concepts, please provide concepts only for beginners.

Pps.We only have 3 weeks to do this project, please consider as well the time and at the same time the level of my expertise(I'm only a student)

Looking forward to your kind response. Thank youuuuu
