weird error causes no responding

envface1=pygame.image.load(p1)
envface2=pygame.image.load(p2)
envface1=pygame.transform.scale(envface1,(768,400))
envface2=pygame.transform.scale(envface2,(768,400))
start = timeit.default_timer()
window.blit(txt[0],(0,0))
window.blit(envface1,(0,400))
window.blit(envface2,(800,400))
pygame.display.flip()
display=False
while not display:
    #delete the print will make it no responding
    print
    keys=pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        display=True
        print "1"
    if keys[pygame.K_RIGHT]:
        display=True
        print "2"
end=timeit.default_timer()
print end-start

pygame.quit()

For this part of code, I am trying to make something that user can choose the picture they like and print the result out. But in the while loop, when I delete the line with "print" only and run it, the program will down and make it no responding. Why would this happen?

As Cyber explained, you have a while loop that runs while display is false. However, since you don't modify display at all inside the loop, you've effectively created an infinite loop.

Your observation that the program will not respond is caused by the fact that nothing happens in the infinite loop unless a key is pressed.
