Smiley Pong Help

[Jasmineleroy]

Hello, I am a STEM teacher in an elementary school. My student have been learning python. We have read the Smiley Pong code, from Teach Your Kids to Code, Chapter 9. We wrote the code exactly from the book, yet the program will run, just we get a blank gray screen. when we click to close the window, we get a momentary flash of what the game looks like. We work on MacBook Air and have the most recent version of Python, 3.7. Our Macs run high Sierra. I attached the code below, can anyone please help? Thank you

colorkey = pic.get_at((0,0))

pic.set_colorkey(colorkey)

picx = 0

picy = 0

BLACK = (0,0,0)

WHITE = (255,255,255)

timer = pygame.time.Clock()

speedx = 5

paddlex = 300

paddley = 550

picw = 100

        if event.type == pygame.QUIT:

            keepGoing = False

    picx += speedx

       and speedy > 0:

            speedy = -speedy

    # Draw text on screen

    draw_string = "Lives: " + str(lives) + " Points: " + str(points)

    text = font.render(draw_string, True, WHITE)

    text_rect = text.get_rect()

    text_rect.centerx = screen.get_rect().centerx

    text_rect.y = 10

    screen.blit(text, text_rect)

    pygame.display.update()

    timer.tick(60)

pygame.quit()      # Exit

Please put everything into a code block and properly indented. Thanyou

hey thank very helpful

I use pygame a lot so I will try my best to help you. I'm at school right now so it may take longer than it would usually for me

---

I don't see what's wrong with it, when I get home in a few hours I'll test it, unless someone else solves it before then

---

I don't know for sure and this probably isn't the problem but try using

screen = pygame.display.set_mode((800,600))

rather than this

screen = pygame.display.set_mode([800,600])

Errors are from double spacing. Python has strict rules with white space.
line 93 and 97 can't be double space.

SimplyPong should been commented out.

used my own image(change it to use your own) and added the end if you reach zero.
best of luck...

if picy + pich >= paddley and picy + pich <= paddley + paddleh \

and speedy > 0:

In addition to Windspar's suggestions, you could alternatively add parenthesis to extend any expression down to the next line as stated in this tutorial. So if you have a long if condition you can prettify it via

    if (picy + pich >= paddley and 
        picy + pich <= paddley + paddleh and
        speedy > 0):
