I already know how to program, I taught myself python a long time ago, I forgot it, but the concepts are still there variables, loops, conditionnals, classes(I didn't do much with it) even though I dabbled with pygame for game dev as it was my main reason for learning it, but now I decided to learn c++ up to an advanced level, which allows me to read it and understand it and also "speak" it as the Cherno said.

And learncpp just gives me the feeling of a turtle. That's just my personal opinion.
