Answer 1

You just need to update the display with this command: pygame.display.update() Place the command at the end of your while running: loop.

pygame.init()

screen = pygame.display.set_mode ((1000,437))

background = pygame.image.load("background.jpg")

running = True

while running:

    screen.fill((255,255,255))
    screen.blit(background,(0,0))  
 
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    pygame.display.update()
