【问题描述】：
希望大家能帮忙。最初由 shell 引发的错误是'nameError: 'pygame' is not defined'，这看起来很奇怪，因为没有太大的改变，我的代码之前运行良好。现在在摆弄代码之后——注释掉行，没什么太激烈的——从 python idle 执行它会引发一个基本的语法错误。违规代码：
pygame.display.update()
如果这一行被注释掉，那么在下一行出现一个新的语法错误；违规代码：
if isItSnap(middleDeck):
我查看了这篇帖子 - 'pygame' is not defined - 但答案不适用。
如果我应该发布整个程序，请告诉我。 pygame 当然是导入和初始化的。
#loop for actual gameplay
while True:
for event in pygame.event.get():
#event.type, check identifier the 'type' of event it is
#pygame.QUIT, all 'type's that an event can be are stored as constants
#in pygame.locals module in fact the 'pygame' preceeding QUIT is unnecessary
#QUIT is contant variable in pygame.locals module. now in our global namespace
#finally to generate an event with type 'QUIT' user clicks red boxed cross on window
if event.type == pygame.QUIT:
terminate()
if event.type == pygame.KEYDOWN and event.key == K_ESCAPE:
terminate()
if event.type == pygame.KEYDOWN:#check
if event.key == pygame.turnCardButton:#anyone can turn card over
#lets us know user wants to flip card
turnCard = True
#turn card, only for computer atm
if turnCard:
turnCard(currentPlayer, middleDeck)
turnCard = False
#draw everything to screen, only need to blit latest card, no need whole screen
#or draw everything end prog just draw the latest card here???
windowSurface.fill(GREEN)#clear screen
displayRect = windowSurface.get_rect()
for cards in middleDeck:
card = pygame.image.load(imageLocator[cards])
#atm there is no rotation, all cards aligned perfectly
windowSurface.blit(card, (displayRect.centerx - CARDX, displayRect.centery - CARDY)
#update screen for user, this when they will try call snap
pygame.display.update()
if isItSnap(middleDeck):
#need users to see card before we enter into loop
#check rules snap, maybe need to timer if noone called can continue turning cards
#clear event list as we want to find player with the QUICK DRAW YEEHAA
pygame.event.clear()
while True:
#CURRENTLY NO SCORE CALLING SLOW IN PLAY
for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
#who has one this round!?
if event.key == playerOneSnapButton:
#player one takes all the cards
player1 = middleDeck + player1
middleDeck = []
#just for now UNTIL ALL DRAWING HAS BEEN OPTIMIZED
windowSurface.fill(GREEN)
pygame.display.update()
break
elif event.key == playerTwoSnapButton:
player2 = middleDeck + player2
middleDeck = []
windowSurface.fill(GREEN)
pygame.display.update()

else:
time.sleep(playSpeed)#to slow game a little

您在上一行中缺少
)windowSurface.blit(card, (displayRect.centerx - CARDX, displayRect.centery - CARDY) -
哦，是的，谢谢你好心的陌生人。
