Sprite not rendering

[Clunk_Head]

here is the modified section of your code. You need to add the draw method to the main game loop and put pygame.display.update() after that.

#sprites.draw(main_surface)
 
while True:
    main_surface.fill(WHITE)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
    
    sprites.update()
    sprites.draw(main_surface)
    pygame.display.update()
    clock.tick(fps)

Cheers for using classes and pygame rects.

Thank you. I knew it was a simple mistake.
