当我将其更改为不时，为什么此尝试循环循环？

Question

我对编码完全陌生，想先做一个猜谜游戏。这就是为什么如果您知道自己在做什么，代码可能看起来非常磨损的原因。我不。如果得到的答案不是y/n，我希望代码循环，但问题是现在即使它收到yes/no 答案，它仍然会循环并不断询问相同的问题。

while not infiniteguessanswer:
    try:
        if numberofchances > 50:
            infiniteguess = input('it seems the number you put it is very high! would you just like infinite guesses instead? Y/N\n')
            if infiniteguess == ['Y', 'y', 'yes', 'yea', 'Yeah', 'Yes'] :
                infiniteguessanswer=True
                numberofchances = math.inf
            elif infiniteguess == ['N', 'n', 'no', 'No'] :
                infiniteguessanswer=True
            if infiniteguess != 'y' and infiniteguess != 'n':
                print('WHY DOES THIS LOOP INFINITELY?????')     
        
        
        if numberofchances < 50:
            print ('alright!')
            infiniteguessanswer=True
    
    except:
        print('ok')

Answer 1

用户输入不能等于整个列表，您需要检查是否包含

infiniteguess in ['Y', 'y', 'yes', 'yea', 'Yeah', 'Yes']

infiniteguess in ['N', 'n', 'no', 'No']

Answer 2

while 循环检查任何值，但不特定于某个类型的值，这就是为什么它会在不考虑值的情况下循环；所以而不是：虽然不是infiniteguessanswer 使用 当infiniteguessanswer 为真或假时：然后执行循环或使用成员资格测试来检查一个值是否为可接受的值，就像这里使用的https://www.tutorialspoint.com/python/membership_operators_example.htm 一样。我刚刚在下面的示例中编辑了您的代码：

While infiniteguessanswer in ['Y', 'y', 'yes', 'yea', 'Yeah', 'Yes', 'N', 'n', 'no', 'No']:
try:
    if numberofchances > 50:
        infiniteguess = input('it seems the number you put it is very high! would you just like infinite guesses instead? Y/N\n')
        if infiniteguess in ['Y', 'y', 'yes', 'yea', 'Yeah', 'Yes'] :
            infiniteguessanswer = True
            numberofchances = math.inf
        elif infiniteguess in ['N', 'n', 'no', 'No'] :
            infiniteguessanswer=True
        if infiniteguess != 'y' and infiniteguess != 'n':
            print('WHY DOES THIS LOOP INFINITELY?????')     
    
    
    if numberofchances < 50:
        print ('alright!')
        infiniteguessanswer=True

except:
    print('ok')

在循环开始之前，您必须请求一个无限猜测答案的值。也许是这样的：infiniteguessanswer = input('Do you want to play infinite guess loop?')
