Can you programm a 3D video game

Answer 1

Yes, you can. Modules like panda3d or pyglet or even pygame would be of a help to you.
Check out a demo I made in Python, quite a while ago:

Sure, it's no Unity or Unreal, but works ;)

Answer 2

In python, the most popular modules for games and graphics are tkinter and pygame. These are used to make 2d games. However, while you can try to make 3d games, developers mostly tend to use game engines and/or C languages.
