In my opinion, whether you learn C++ or if you learn Python, the language doesn't matter as much as the logic and fundamentals of programming (i.e. logic, matrices, memory management). Learning a new syntax is just a two week adjustment for good programmers.
Rather than getting straight into C++, you should do a little research on what you really want in your future and what kind of games you want to make. I'm saying that because C++ is a lot to learn for an introductory language.
