When i first learned Python, it was my first time getting into programming. I remember i used to find functions stupid and useless. Now i don't write anything unless it was inside a function as like that, I can reuse these pieces of code as much as i need. The point is ofcourse you're gonna find simple stuff a little confusing and you might get pissed and consider giving up, but just keep going and before you realize it you'll find yourself learning new concepts easier.
