title: How can I make two windows show at the same time?
body: <p>I am trying to make a game with pygame and face recognition. In order to do that I need to windows open. The one with the face recognizing one and one with the game one. But when I imported the face_recog.py , the game window wouldn't show until the face_recog would be closed. What should I do??</p>
  
  <p>I tried importing in side the while of the game.py file</p>
  
  <p>...python game.py code</p>
