[PyGame] PyGame does not close when I press the close button

[Midnight_Sparkle3344]

you should never use sys.quit to exit a program. You should let the program run to the end of the script. Your problem is you need pygame.quit() if i recall in combo with IDLE to quit properly.

running = True

while running:
...
   if event.type == pygame.QUIT:
      running = False

and then at the very end of the script put

pygame.quit()

Thank you. That worked.
