title: How check, if button pressed twice?
body: <p>I am able to press the Enter button in Python, using Pygame.
  Now, it prints "once" into the console everytime I press the button.
  How can i detect if the button is pressed more than once and print "more than once"?</p>
  
  <pre><code>  press = False
    if event.key == pygame.K_RETURN:
        press = True
  
        print("once")
    if press == True:
        print("more than once")
  </code></pre>
