Question

我试着让它只问“你想继续”3次，但它似乎没有用，它只是继续运行。我该如何解决？这是一个聊天响应程序，计算机提出一个问题和用户响应。

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()

Answer 1

达尔瓦克的评论是正确的。如果你想保持其余的代码相同，那么我只想修改restart函数看起来像这样：

import sys

def restart():
    if input('do you want to continue? ') != 'yes':
        sys.exit()

这样，如果用户使用“是”之外的任何内容进行响应，该程序将退出;但是，如果他们回答“是”，那么对restart的调用就什么都不做了，你的循环应该进入下一次迭代。

还有一点需要注意：不建议在程序中调用exit函数，因为它只是在您运行Python解释器时使用的辅助函数。在程序中，您应导入sys模块并致电sys.exit。资料来源：Difference between exit() and sys.exit() in Python
