The game loop

Games run in a loop about 10 to 60 times a second: handle events, update the game, draw everything. clock.tick() controls the speed.

Key points

Events, update, draw
QUIT event when the window closes
clock.tick(10) = 10 frames a second

clock = pygame.time.Clock()
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    screen.fill((10, 16, 32))
    pygame.display.flip()
    clock.tick(10)
pygame.quit()

Your turn

Add the game loop. The window should stay open until you close it.
