title: Python programming for card game War
body: <p>This program is supposed to play the card game War. Okay so I need to be able to prompt the user to keep playing and have them respond by hitting the enter key. I'm not sure how to make this happen. Help?</p>

  the_deck.display()

      player. It sorts the rank so as to solve the problem
      with Aces causing an infinite game'''
