python - 我用 python 做的测验不起作用

Question

我最近在我的计算机科学课上做了一个测验，但由于某种原因它没有用，我是编程新手，我想知道也许你能帮助我，我知道这会很简单，但正如我所说， 我是新来的。我只复制了 8 个问题中的 4 个问题，但出于某种原因，它忽略了 IF 语句并直接转到 else 语句。代码如下:

score=0
print("Welcome the the general knowledge quiz")
your_name = input("What is your name?: ")

input("Press Enter to Start the Quiz!")

print("1) Who presents Pointless?")
answer = input()
if answer == ["Alexander Armstong", "alexander armstrong", "ALEXANDER  
ARMSTRONG"]:
    print("Well done", your_name)
    score = score+1
else:
    print("Sorry, the answer was Alexander Armstrong")
print("Your score is", score)


print("2) Who presents I'm a celeb, get me out of here?")
answer = input()
if answer == ["Ant and Dec", "ant and dec", "ANT AND DEC", "Ant And Dec"]:
    print("Well done", your_name)
    score = score+1
else:
    print("Sorry, the answer was Ant and Dec")
print("Your score is", score)


print("3) What is the capital of England?")
answer = input()
if answer == ["London", "london", "LONDON"]:
    print("Well done", your_name)
    score = score+1
else:
    print("Sorry, the answer was London")
print("Your score is", score)


print("4) Who lives on the White house right now?")
answer = input()
if answer == ["Obama", "obama", "Barack Obama", "barack obama"]:
    print("Well done", your_name)
    score = score+1
else:
    print("Sorry, the answer was Barack Obama")
print("Your score is", score)

Answer 1

answer = input()
if answer == ["Alexander Armstong", "alexander armstrong", "ALEXANDER  
ARMSTRONG ):

除了缺少引号，这个 if 语句总是会失败。 input() 总是返回一个字符串，但您正在检查它是否等于一个列表，这永远不可能是真的。如果将 == 替换为 in，它将执行您期望的操作。

此外，您应该考虑使用 .lower() 将答案变成小写，这样您就只有一个值需要检查。
