Can i make Windows or iOS games in Python ?

Answer 1

Yes, you can. But it is generally better to stick to native platform languages.
First thing is that you won't be able to compile a Python script into a standaolne program and always have to use an interpreter (in this form or another). You can make executables, but they will have to contain Python itself and any (whole!) modules you use.

Answer 2

people usually use PyGame for window games(that is, if you want to use python), c# for iOS games, and Java for Android apps

Answer 3

Yes, you can, but it is not a good idea.
