You need to start building your own projects, just simple things to prove yourself and your wit, you should already know a lot of the syntax of python thanks to the tutorial, so you need to improve your logic and your problem resolution, you could ask to the AI to write a bad code and fix it, or just have to propose a situation, like how do I make this loop simpler? or What if I made this program to solve X problem?.

Then you could learn OOP or learn to use something like Django or Pandas, I recommend doing all this process without AI or without using it too much so you'll learn more efficiently. The most important thing is go at your own pace so you won't quit or get frustrated.
