我正在运行这个小程序，它以全屏模式将图像加载到屏幕上，但是一旦加载，程序将不会通过任何组合键退出，我最终不得不重置计算机才能完成我正在做的任何其他事情。
import pygame
pygame.init()
WIDTH=1366; HEIGHT=768
screen = pygame.display.set_mode((WIDTH, HEIGHT), pygame.FULLSCREEN)
pygame.display.set_caption('Katso')
PENGUIN = pygame.image.load("assets/download.png")
MICKEY = pygame.image.load("assets/mickey.jpg")
ADV = pygame.image.load("assets/adv.jpg")
CAT = pygame.image.load("assets/cat.jpg")
FLV = pygame.image.load("assets/flavours.jpg")
HALL = pygame.image.load("assets/hallway.jpg")
x = 0; # x coordnate of image
y = 0; # y coordinate of image
screen.blit(PENGUIN,(x,y)); pygame.display.update()
running = True
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.QUIT()
if event.type == pygame.KEYDOWN and event.key == pygame.K_1:
screen.blit(MICKEY,(x,y)); pygame.display.update()
if event.type == pygame.KEYDOWN and event.key == pygame.K_2:
screen.blit(PENGUIN,(x,y)); pygame.display.update()
if event.type == pygame.KEYDOWN and event.key == pygame.K_3:
screen.blit(ADV,(x,y)); pygame.display.update()
if event.type == pygame.KEYDOWN and event.key == pygame.K_4:
screen.blit(FLV,(x,y)); pygame.display.update()
if event.type == pygame.KEYDOWN and event.key == pygame.K_5:
screen.blit(CAT,(x,y)); pygame.display.update()
if event.type == pygame.KEYDOWN and event.key == pygame.K_6:
screen.blit(HALL,(x,y));pygame.display.update()
pygame.QUIT()
pygame.QUIT是一个常量值（整数），用于检查事件的类型。要取消初始化 pygame，你必须调用pygame.quit()（小写），但这实际上并不会退出你的游戏，而只是取消初始化加载的 pygame 模块。我认为如果您在 IDLE 等基于 tkinter 的编辑器中开始游戏，则只需要关闭窗口。
要退出游戏，你可以跳出 while 循环，让 Python 像往常一样结束程序，或者你可以调用sys.exit().
Since you can't click on the 'x' button to close the window in fullscreen mode, you have to use a key like Esc.
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_ESCAPE:
running = False # Set running to False to end the while loop.
