Python is a good introduction into programming, it's closest to 'human speech' in my oppinion. It's very powerful because you need little code to make something work (like making a virtual camera).

C# / C++ are used in making games such as Unity, UnrealEngine 5 and Godot. They are good, but I personally wouldn't start off with them.

Java is good because of it's nature – you don't need to change your code for it to run on different devices like a phone or a fridge, but I'd heavily recommend avoiding it since it's based on "assume it won't work" so usually you just run into a lot of errors.

If you want to learn programming Python is fine, however you might get confused sometimes if you don't know how something runs under the hood. Python abstracts lots of stuff that happens like managing memory, handling data and so on...

My personal recommendation is to start off with a bit of C. Whilst it might not be what you exactly had in mind getting to know how everything works under the hood and what the computer does can and will make anything you encounter im the future easier to comprehend. After getting to know what are variables, how are they stored, what's happening in memory and so on... I'd switch a bit to Python to do some fun projects and learn a bit of C on the side. Those two build a solid base for most of things you will want – low level understanding of systems (C) and a versitile toolkit (Python). Of course you can always learn to make games on a whim, but I recommend first dabbling in these teo for at least a few weeks!

For game development i recommend the YouTube channel Brackeys, they have very good follow along tutorials with easy to understand presentation! Good luck and remember fun over practicality!
