我有一個測驗，在最后一輪，如果它的值不正確，我希望它結束
我有一個if回圈，但我希望我的最終else值能夠轉到行號代碼，因為它是一個長代碼。為了使用此功能，我如何查看行號（我使用Portable Python Scripter）。

uj5u.com熱心網友回復：
使用回圈和函式可以幫助你使這段代碼更短一些，并消除很多復制 粘貼 if/else 的需要。這是對初始測驗部分的快速重寫，其中包含一個main()函式的概要，以便為您提供想法：
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()
將代碼放在函式中意味著當需要結束時，您可以return讓函式的其余部分在縮進的外部級別繼續，而不必進入越來越深的嵌套if/elif/else陳述句來繼續程式。使用回圈（如first_round上面的函式）意味著您不需要一遍又一遍地復制和粘貼相同的代碼。
采用上面的模式并將其應用于死亡回合，我們可能會得到類似的結果：
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
請注意return在“不正確”的情況下，這是此函式與 不同的一種方式first_round，也是它的原因，因此您不需要一個goto或五個不同的嵌套else陳述句來跟蹤可能結束游戲的五個不同時間-- 只要有一個錯誤的答案，函式就會回傳，然后main可以查看最終分數并根據它的值做不同的事情。
在您進行測驗時要考慮的另一件事 - 現在它對準確的措辭和大小寫非常敏感，即使您提供了多個正確的選項。例如：
What does Harry say the best thing a girl can wear is?Her smile
Incorrect
這是修復它的一種方法，可以使任何包含“微笑”一詞的答案都被接受，無論大小寫：
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!
