Re: [pygame] pygame.error: video system not initialized

Hi Alex and Jake,

Passing the display surface around is not the problem. In fact it is 
good style to keep a reference and pass it to other functions as an 
argument. It lets you reuse those functions for other surfaces if you 
want. I agree with Jake about seeing  the complete program before 
hazarding a guess. It could be something as trivial as calling 
pygame.event.get() after pygame.quit():

>>> import pygame
>>> pygame.init()

>>> win = pygame.display.set_mode((200, 100))
>>> win.fill((0, 0, 255))
<rect(0, 0, 200, 100)>
>>> pygame.display.flip()
>>> evts = pygame.event.get()
>>> pygame.quit()
>>> evts = pygame.event.get()
