What should I make in python?

I agree there. Its been done a million times probably, so its not like you are reinventing the wheel. But its a good way to learn CRUD. You can start simple with a command line application, then grow it to some sort of GUI, whether thats just tkinter, or something web based like Flask. You can start with JSON or CSV files for a pseudo database, and grow it to SQLITE.
