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/ Module, if it's okay with you please share it with me. Looking forward to your kind response. Thank youuuuu
