行号并转到行
Line numbers and go to line
我有一个测验，在最后一轮，如果它得到一个不正确的值，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 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）。

使用循环和函数可以帮助您大大缩短此代码，并消除大量复制+粘贴的需要 if/else。这是对初始测验部分的快速重写，其中包含一个 main() 函数的轮廓，旨在为您提供思路：
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()
将代码放在函数中意味着当它结束时，您可以 return 并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的嵌套 if/elif/else 语句来继续程序。使用循环（如上面的 first_round 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“不正确”情况下的 return，这是此函数与 first_round 不同的一种方式，也是它的特点，因此您不需要 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——一旦出现错误答案，函数 returns，于是 main 可以查看最终得分并根据其值做不同的事情。
做测验时还要考虑一件事——现在它对精确的措辞 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
这里有一种修复方法，无论大小写，任何包含“微笑”一词的答案都将被接受：
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!
