TL;DR for most of the above, but you sound like someone who knows nothing about programming (no offense). In this case, don't even bother with C++. You won't have a use for it and it is far too advanced to attempt.
Stick with something simple and extremely useful in a wide variety of situations. Python is good, but I would honestly start off with Javascript. I recommend a website called codecademy for learning Javascript.
EDIT: Javascript is useful from web design all the way to game design in the Unity engine. Perfect language for a beginner IMO
