Python 2D games w/o external libs?

Hey guys.

I wonder, is it possible to create a sprite-based game using Python without any external libraries?
I mean GUI games, obviously. Not console-based ones :stuck_out_tongue:
I am intending to try my hand at 2D games, but I’d like Python to be my lingo and I’d like it to be playable on other OSs as well.

So, what do you think?

you’ll need pygame

Yes, I know about it. But that’s what I mean with an external Lib.
I was wondering if something like Tkinter could do it. But Tkinter is not advanced enough I guess
