到达特定行后如何停止程序？

Question

我正在尝试用 python 创建一个游戏，一个名为“谁想成为百万富翁？”的多项选择游戏。问题是一旦用户未能回答第一个问题，我希望程序停止执行第二个问题。print("What is the tallest being in existence?")input(("If you want to see the choices just press enter. " + name))print("Is it A, Dinosaur?")print("B, The one and only, Giraffe")print("C,The soul of the ocean Whale")print("or D, None")print("So what do you believe is the answer ? " + name + " ")answer_1 = input()if answer_1 == Q1_answer:    print("Correct! You Have Earned 100,000$ ")    score = +100000if answer_1 != Q1_answer:    print("Im sorry, You have lost the game.")print("Which famous inventor was born in 1856?")print("A Einstein")print("B, Tesla")print("C, Napoleon")print("D, Newton")answer_2 = input()if answer_2 == Q2_answer.lower():    print("Correct! It is Tesla Indeed, Your reached  200,000$ ")    score = +100000else:    print("Sorry, wrong answer. You have lost and earned 0$. ")

Answer 1

我认为你可以用更好的方式编写你的程序，目前你不能轻易地添加问题，因为你必须为每个新问题重复整个代码。您可以将所有问题存储在一个列表中，然后遍历它们。sys.exit()由于我组织代码的方式，我也不需要。这是代码：

questions = [

    {

        "question": "What is the tallest being in existence?",

        "options": [

            "Is it A, Dinosaur?",

            "B, The one and only, Giraffe",

            "C,The soul of the ocean Whale",

            "or D, None"

        ],

        "correctOption": "a",

        "prize": 100_000

    },

    {

        "question": "Which famous inventor was born in 1856?",

        "options": [

            "A Einstein",

            "B, Tesla",

            "C, Napoleon",

            "D, Newton"

        ],

        "correctOption": "b",

        "prize": 100_000

    }

]

isGameWon = True

score = 0

for question in questions:

    print(question['question'])

    input("If you want to see the choices just press enter.")

    for option in question['options']:

        print(option)

    print("So what do you believe is the answer?")

    answer = input()

    if answer.lower() == question['correctOption']:

        score = score + question['prize']

        print("Correct! You Have Earned $" + str(score) + ".")

    else:

        isGameWon = False

        break

if (isGameWon):

    print("Congrats! You have won the game. You earned $" + str(score) + ".")

else:

    print("Sorry, wrong answer. You have lost and earned $0.")

Answer 2

如果你想完全退出程序你需要调用exit方法。

import sys

...    

if answer_1 != Q1_answer:

    print("Im sorry, You have lost the game.")

    sys.exit()

Answer 3

您可以使用 exit() 退出程序。我会打印一条消息，告诉用户程序将退出。
