What would be the best project for expert level in Python?

Question

Doesn't mean I'm an expert but just wanted to know the potential of Python !! Go ahead mention your most difficult yet most useful & effective programs u've ever made using Python :)

Answer 1

The hardest project in my opinion will be to make a code that contains everything you have learned.
For example first you make a very easy code and then complicate it as much as you can😉

And if you want here is my most difficult code I've made so far. I'll be glad if you like it.
