我想结束这个循环，但在结束时使用 break 似乎不起作用。我希望循环在用户输入所有三个选项后结束；年龄、笑话和事实。
请您参考如下方法:
您可以将用户查询的状态记录在一个集合中:
chosen = set()
while len(chosen) < 3:
inp = raw_input()
if inp == "":
pres = input("What would you like to know about me? AGE, JOKE, FACT")
if pres in {'AGE', 'Age','age'}:
print("I was birthed from my mother 87 years ago. Press enter to continue")
chosen.add("age")
if pres in {'JOKE','Joke','joke'}:
print("Where do polar bears keep their money?")
import time
time.sleep(2)
print("In a snow bank! Press enter to continue")
chosen.add("joke")
if pres in {'FACT','Fact','fact'}:
print("Hippopotamus's have pink spit! Press enter to continue")
chosen.add("fact")
