I know a little bit of C++ and Python, but I am not too sure which program would be better for programming a mobile game.

And also, is there tools that I can use for this?

There are a few packages around for Python, such as Kivy, Brython, etc. C++ is also pretty good, you can check out this thread for a rundown on some options. You could also give Unity a look.

Thank you, Sysop-Delco!
