我有一个测验，在最后一轮，如果它的值不正确，我希望它结束

我有一个if循环，但我希望我的最终else值有一个转到行号代码，因为它是一个长代码。为了使用此功能，我如何查看行号（我使用Portable Python Scripter）。

print("PLEASE NOTE: Answers are case-sensitive, so start all answers with a capital letter.")
print("Getting full marks (5/5) in each round will allow you to complete the next round.")

使用循环和函数可以帮助您缩短这段代码，并消除大量复制+粘贴 if/else 的需要。这是对初始测验部分的快速重写，其中包含一个main()函数的大纲，以提供您的想法：

def first_round():
    """Ask the first round questions, return cumulative score."""
    score = 0
    for question, answers in [
        ("What boyband was Harry Styles in?",
            {"One Direction", "White Eskimo"}),
        ("What is Harry's birthday (write in format dd/mm/yyy)",
            {"01/02/1990"}),
        ("What is Harry's favourite film?",
            {"Love, Actually", "Love Actually"}),
        ("What war film did Harry star in?",
            {"Dunkirk"}),
        ("What is Harry's mum's first name?",
            {"Anne"}),
    ]:
        if input(question) in answers:
            print("Correct!")
            score += 1
        else:
            print("Incorrect")
    return score


def main():
    # do intro stuff here

    score = first_round()
    if score < 5:
        print(f"You achieved {score}")
        return  # Game over!

    print("Well done! You got everything correct!")
    print("Entering quickfire round...")

    # continue on with score = quickfire_round()...


main()

将代码放入函数中意味着当该结束时，您可以return让函数的其余部分在缩进的外层继续，而不必进入越来越深if/elif/else的嵌套语句来继续程序。使用循环（如first_round上面的函数）意味着您不需要一遍又一遍地复制和粘贴相同的代码。

采用上面的模式并将其应用于死亡回合，我们可能会得到类似的结果：

def death_round():
    """Ask the death round questions -- first wrong answer ends it!"""
    score = 0
    for question, answers in [
        ("What characer does Harry play in the MCU (Marvel Cinematic Universe)?",
            {"Starfox", "Eros"}),
        ("What does Harry say the best thing a girl can wear is?",
            {"A smile", "Smile"}),
        ("What did Harry dress up as for 2021's 'Harryween'?",
            {"Alice", "Alice in Wonderland", "A clown", "Clown"}),
        ("Which singer does Harry have a crush on?",
            {"Adelete"}),
        ("How many nipples does Harry have?",
            {"Four", "4"}),
    ]:
        if input(question) in answers:
            print("Correct!")
            score += 1
        else:
            print("Incorrect")
            return score  # sudden death!
    return score

请注意return在“不正确”的情况下，这是此函数与 不同的一种方式，也是导致first_round它的原因，因此您不需要一个goto或五个不同的嵌套else语句来跟踪您可能结束游戏的五个不同时间-- 一旦有错误的答案，函数就会返回，然后main可以查看最终分数并根据其值做不同的事情。

在您进行测验时要考虑的另一件事 - 现在它对准确的措辞和大小写非常敏感，即使您提供了多个正确的选项。例如：

What does Harry say the best thing a girl can wear is?Her smile
Incorrect

这是修复它的一种方法，它将使得任何包含“微笑”一词的答案都将被接受，无论大小写如何：

for question, answers in [
    ("What does Harry say the best thing a girl can wear is?",
        {"smile"}),
    ("What did Harry dress up as for 2021's 'Harryween'?",
        {"alice", "clown"}),
]:
    answer = input(question).lower()
    if any(a in answer for a in answers):
        print("Correct!")
    else:
        print("Incorrect")

What does Harry say the best thing a girl can wear is? Just a smile
Correct!
What did Harry dress up as for 2021's 'Harryween'? A fabulous clown
Correct!
