Pygame error : video system not initialized [duplicate]

问题

import sys,pygame
pygame.init()

size = width , height = 600,400 
screen = pygame.display.set_mode(size)

tux = pygame.image.load("tux.png")

screen.blit(tux,(200,200))
screen.blit(tux,(0,0))
pygame.display.flip()

while 1:
ev = pygame.event.poll() 
if ev.type == pygame.QUIT:
    pygame.quit()

The above code is showing this error

    14         if ev.type == pygame.QUIT:
    15             pygame.quit()

error: video system not initialized

I am very new to pygame , what is this error and how to remove it ? PS: tux is the png image i am using in this file

回答1:

You don't break your while loop after calling pygame.quit().

Just use

while 1:
    ev = pygame.event.poll() 
    if ev.type == pygame.QUIT:
        break
pygame.quit()

or something like that. Otherwise, you'll call pygame.event.poll() after pygame.quit() on the next iteration of the loop, which will lead to your error.
