Pygame in 90 Minutes - For Beginners syntax issues

[Windspar]

Just a few typos. This is mainly use for testing.

# It double underscore.
if __name__ == '__main__':
    # It lower case main to match your function.
    main()

Example

import pygame

def main():
    # Active all pygame modules.
    pygame.init()
    surface = pygame.display.set_mode((900, 500))
    # Get the area of the surface as a rect.
    rect = surface.get_rect()
    clock = pygame.time.Clock()
    fps = 60

    run = True
    while run:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                run = False

        surface.fill('black')
        # Render surface to screen.
        pygame.display.flip()
        # Let the computer do other jobs or rest.
        clock.tick(fps)

    pygame.quit()

main()
