嗨。这是我制作的python hangman游戏，但每次运行时都会出现这个错误。我不知道这个错误意味着什么。有人知道是什么导致了这个错误吗？否则效果很好。 谢谢！在

这可能不是唯一的问题，但在您发布的示例中，尽管“n”是“penney”的一部分，但仍得到ValueError的原因是因为您从未重置increment，并且当您对字符串调用index时，它被用作搜索的开始。在

由于您在第二次尝试时输入了“e”，因此增量将等于3，并且从那里开始，它将永远找不到“n”。在

这是你的原始代码的一小部分，我修改了它，使它可以工作。我去掉了增量。在

if letter in words2:

    print('The letter is in the word.')

    place = -1
    while words2.count(letter)!=blankword.count(letter):

        place=words2.index(letter, place+1)
        blankword[place]=letter
        blankword2=''.join(blankword)
        i=i+1
