Question

当打印“你闻到有趣的特朗普！”时，我想停止while循环。该代码确实停止了，但是并没有停止在正确的句子上，我在这里做错了什么？

while True:

  from time import sleep
  from random import randint

  greetings = ["Hello","Howdy","You smell funny"]
  title = ["Human.", "Trump!" , "Maid."]
  greeting = "{x}, {y}".format(x=greetings[randint(0,2)], y=title[randint(0,2)])

  if greeting == "{x}, {y}".format(x=greetings[2], y=title[1]):
    break
  else:
    sleep(0.3)
    print(greeting)

Answer 1

当它碰到break并停止循环时，它尚未打印“问候语”。只需将print(greeting)移动到if greeting == ...之前即可。

Answer 2

您可以使用标志而不是'break'退出循环。

Break_Flag=True
while Break_Flag:
    from time import sleep
    from random import randint
    greetings = ["Hello","Howdy","You smell funny"]
    title = ["Human.", "Trump!" , "Maid."]
    greeting = "{x}, {y}".format(x=greetings[randint(0,2)], y=title[randint(0,2)])
    if greeting == "{x}, {y}".format(x=greetings[2], y=title[1]):
        print(greeting,"Stop")  
        Break_Flag=False
    else:
        sleep(0.3)
        print(greeting)

满足条件时，while循环不会停止
