我得到的结果是。

    Welcome to Hangman! Guess the mystery word with less than 6 mistakes!
Please enter an integer number (0<=number<10) to choose the word in the list:4
The length of the word is:  6



   Please enter the letter you guess: p
The letter is in the word.
Letters matched so far:  p_____

Please enter the letter you guess: e
The letter is in the word.
You have found the mystery word. You win!
Letters matched so far: pe__e_
Goodbye!

您好。这是我制作的蟒蛇刽子手游戏，但每次运行时我都会收到此错误。我不知道这个错误意味着什么。有谁知道导致此错误的原因是什么？否则它工作正常。谢谢！

这可能不是唯一的问题，但是你在你发布的例子中得到ValueError的原因即使'n'是'penney'的一部分也是因为你从未重置increment并且它被使用了当你在字符串上调用index时作为搜索的开始。

由于你在第二次尝试时输入'e'，增量将等于3并从那里开始，它将永远不会找到'n'。

这是我修改的原始代码的一小部分，以使其有效。我摆脱了增量。

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

builtins.ValueError：'e'不在列表中
