在python 3.6中多次运行代码

我试着让它只问“你想继续吗”3次，但它似乎不起作用，只是继续运行。我该如何解决这个问题？这是一个聊天响应程序，计算机问一个问题，用户回答

def choice():
        prompts = [feeling, homesick, miss]
        random.choice(prompts)()

for item in range(3):
    choice()

这是我为它编写的代码。但它不起作用

 import random
    
    name = input("What is your name? ")
    
    def restart():
        restart=input('do you want to continue? ')
        if restart=='yes':
            choice()
        else:
            print("ok, see you later!")
            exit()
            
    def feeling():
        response = input("How are you feeling right now {name}?".format(name=name))
        if response == "tired":
            tired = ['I wish I can make you feel better.','I hope school is not making you feel stressed.','You deserve the right to relax.']
            print(random.choice(tired))
            restart()
        else:
            print("Sorry, I don't understand what you mean by "+response+".")
            exit()
    
    def homesick():
        response = input("Do you miss your home? ")
        if response == "yes":
            yes=["Don't worry, you will be home soon......",'I am protecting your family and loved ones, trust me on this.',"Your kingdoms has been waiting for a long time, they'd forgiven your mistakes"]
            print(random.choice(yes))
            restart()
        else:
            print("Sorry, I don't understand what you mean by "+response+".")
            exit()
    
    def miss():
         response = input("Who do you miss?")
         if response == "my mom":
             print("Mom will be in town soon")
             restart()
         else:
            print("Sorry, I don't understand what you mean by "+response+".")
            exit()
    
    def choice():
        prompts = [feeling, homesick, miss]
        random.choice(prompts)()
    
    for item in range(3):
        choice()

达瓦克的评论是正确的。如果您想保持代码的其余部分不变，那么我只需修改

restart

函数，使其看起来像这样：

导入系统 def restart（）： 如果输入（'您想继续吗？'）！='是的： sys.exit（） 这样，如果用户的响应不是“是”，程序将退出；但是，如果它们的响应为“yes”，那么对

restart

的调用将不起任何作用，并且您的循环应该前进到下一个迭代

还有一点需要注意：不建议在程序中调用

exit

函数，因为它只是运行Python解释器时要使用的辅助函数。在程序中，您应该导入

sys

模块并调用

sys.exit

每当你从感觉、想家或想念中执行restart（）方法时，你总是执行choice（）方法，所以它会再次询问你，直到你回答其他一些感觉“累了”的问题，“是”表示想家，或“我妈妈”表示想念。试着为提出这些问题的机制找出更好的流程。可能尝试添加一些计数器，这将在第三个问题“是否要继续”后终止脚本
