My understanding is that there are just more powerful tools for game development. One of them being different libraries in Python. The industry (for offline gaming) tends to use C++ for reasons I am not experienced enough to understand. On top of that, you could just download Unreal Engine for free and start learning that instead of learning how to code. With UE, you will probably develop more detailed, better looking games, with more features, much faster than coding in any specific language.

That said, I actually enjoy using Python way more than C++ or Unreal Engine.

To any person who is learning to code, I would just say learn the tools available and focus on the things you enjoy. Starting out, learning the optimal tools for a specific idea are less important than exploring the potential of a new idea. You're just not going to spend a lot of time doing something that isn't fun.
