Beginning the Pong Program

You can use copy / paste to get this code into Python so you don't have to type it again. (I wanted you to type it the first time so that you could begin to learn Python.)

# Import the pygame library and initialize the game engine
import pygame
pygame.init()

# Define some colors
BLACK = (0,0,0)
WHITE = (255,255,255)

# Open a new window
size = (700, 500)
screen = pygame.display.set_mode(size)
pygame.display.set_caption("Pong")

# The loop will carry on until the user exits 
# the game (e.g. clicks the close button).
carryOn = True


# The clock will be used to control how fast 
# the screen updates
clock = pygame.time.Clock()

# -------- Main Program Loop -----------
while carryOn:
# --- Main event loop
    for event in pygame.event.get(): 
    # User did something
        if event.type == pygame.QUIT: 
        # If user clicked close
              carryOn = False 
		    # Flag that we are done 
		    # so we exit this loop
 
# --- Game logic will go here

# --- Drawing code should go here
    # First, clear the screen to black. 
    screen.fill(BLACK)
    # Draw the net
    pygame.draw.line(screen, 
       WHITE, [349, 0], [349, 500], 5)
    # --- Update the screen
    pygame.display.flip()

# Once we have exited the main program loop 
# we can stop the game engine:
pygame.quit()
