Does it have any color?

# Define some colors

Reveal yourself!

# Define the name of the screen

But it just closes!!

# Loop until the user clicks the close button.

# Used to manage how fast the screen updates

# -------- Main Program Loop -----------
while not done:
    # --- Main event loop
    for event in pygame.event.get(): # User did something
        if event.type == pygame.QUIT: # If user clicked close
            done = True # Flag that we are done so we exit this loop

  # --- Game logic should go here
    # --- Drawing code should go here
    # First, clear the screen to white. Don't put other drawing commands
    # above this, or they will be erased with this command.
    screen.fill(WHITE)
    # --- Go ahead and update the screen with what we've drawn.
    pygame.display.flip()
    # --- Limit to 60 frames per second
