Question

print("Hi im a PC and my name is Micro, What's your name?")
name = raw_input("")
print("Hi " + name + " how are you, are you good?")
answer = (raw_input(""))
if answer == "yes":
           print("That's good to hear!")
elif answer == "no":
           print("Oh well")
while answer != ("yes","no")
           print("Sorry, you didnt answer the question properly, Please answer with a yes or no.")
print"I'm going to sleep for 5 seconds and then i'll be back."
import time
time.sleep(5)
print"I'm back!"

需要为是或否位创建一个循环，任何人都知道如何？谢谢你的帮助！

Answer 1

使用while True:，当您想要停止循环时，请使用break。

这将是您的代码：

...
while True:
    answer = (raw_input(""))
    if answer == "yes":
        print("That's good to hear!")
        break
    elif answer == "no":    
        print("Oh well")
        break
    else:
        print("Sorry, you didnt answer the question properly, Please answer with a yes or no.")
...

现在换一个完全不同的东西：

options = {'intro':"Hi, I'm a PC and my name is Micro, What's your name? > ",
           'ask':  "Hi %s how are you, are you good? > ",
           'yes':  "That's good to hear!",
           'no':   "Oh well",
           'error':"Sorry, you didnt answer the question properly\n",
           'hint': "Please answer with yes/no"}

name = raw_input(options['intro'])

while True:
    try:
        answer = raw_input(options['ask'] % name)
        print options[answer.lower()]
        break
    except KeyError:
        print options['error'], options['hint']

正如你所说的你是Python中的菜鸟，我想在这里介绍几个新的东西来补充你可能会觉得有用的其他答案。
