No problem! Take it as slow as you need, programming is super confusing when you first try it. That tutorial was javascript! I wouldn't try python myself, it's not really suitable for games.
I use C# (C sharp) myself, with Monogame. Monogame is a library that gives you all the tools for drawing, handeling input and all that stuff.
This game was made for a gamejam, which is now over. I'm working on improving the engine now for my next game, when it's done I might add some new stuff to this game :) Will be a while though, making an engine is a lot of work!
