如果循环使用零件不是elif部分？

Question

我正在尝试编码一个吊具游戏，其中它隐藏了一个单词的字母，一旦您猜到某些字母，它就会取代每个字母。

当我得到错误的答案时，我想将其放入一个列表中，我可以打印并向用户展示错误的字母数量（以便我可以做hangman绘图）。

我可以让它进入列表一次，然后一旦我做了正确的字母，它就不起作用了，我必须再次重新重新重新重新注释正确的字母。然后，我去错了一封错误的信，它不再起作用，我会遇到错误：

valueerror：找不到子字符串 - 位置=（word.index（uphus_letter））

我认为它正在使用上述内容，并且我不确定如何修复它。这就是循环的样子：

if guess_letter in list_of_letters:
    position = (word.index(guess_letter))
    print(hiding.replace(hiding[position], guess_letter))
    hiding = hiding.replace(hiding[position], guess_letter)
    correct_guess_amount += 1

while correct_guess_amount <len(word):
    if guess_letter in list_of_letters:
        guess_letter = input('enter a letter: ')
        position = (word.index(guess_letter))
        print(hiding.replace(hiding[position], guess_letter))
        hiding =  hiding.replace(hiding[position], guess_letter)
        correct_guess_amount += 1
        print(correct_guess_amount)
    elif guess_letter not in list_of_letters:
        incorrect_guess_amount += 1
        incorrect_list.append(guess_letter)
        print(incorrect_list)
        print(incorrect_guess_amount)
        guess_letter = input('enter a letter: ')
        if guess_letter in list_of_letters:
            guess_letter = input('enter a letter: ')
            position = (word.index(guess_letter))
            print(hiding.replace(hiding[position], guess_letter))
            hiding = hiding.replace(hiding[position], guess_letter)
            correct_guess_amount += 1
            print(correct_guess_amount)

问题源于以下事实：您正在让用户输入之后的猜测您已经检查了猜测>猜测是否在word中。您的循环应该看起来像

while correct_guess_amount < len(word):
    guess_letter = input("...")
    if guess_letter in word:
        # now you can safely call word.index(guess_letter)
    else:
        # handle the wrong answer case
