为什么不能同时按下两个按钮？
答案 0 :(得分：2)
尝试一下：
pygame.event.get()在您的版本中，您正在pygame.key.get_pressed()上进行迭代，并且您仅评估for循环中的最后一个事件（除quit逻辑以外），这意味着您仅评估最后一个按键。将代码移入循环，您可以评估所有事件。
如果要检测多个按键，请使用finish = False
while not finish:
for event in pygame.event.get():
if event.type == pygame.QUIT:
finish = True
keys = pygame.key.get_pressed()
if keys[pygame.K_LEFT]:
print("C")
if keys[pygame.K_RIGHT]:
print("B")
if keys[pygame.K_UP]:
print("A")

键盘事件（例如pygame.KEYDOWN）仅在按下按钮时发生一次。
使用pygame.key.get_pressed()连续评估按钮的状态。例如：
finish = False
while not finish:
for event in pygame.event.get():
if event.type == pygame.QUIT:
finish = True
keys = pygame.key.get_pressed()
if keys[pygame.K_UP]:
print "A"
if keys[pygame.K_RIGHT]:
print "B"
if keys[pygame.K_LEFT]:
print "C"
或者，如果您希望获得列表：
finish = False
while not finish:
for event in pygame.event.get():
if event.type == pygame.QUIT:
finish = True
keys = pygame.key.get_pressed()
if any(keys):
kmap = {pygame.K_UP : "A", pygame.K_RIGHT : "B", pygame.K_LEFT : "C"}
sl = [kmap[key] for key in kmap if keys[key]]
print sl
