用相同的项目替换列表中相同的每个项目

Question

我正在尝试纠正迭代列表中每个项目的代码，以将所有匹配的项目替换为相同的项目。目前，仅替换第一个实例。它适用于刽子手风格的游戏。这是我的代码：

    if guess in self.word:
        print(f"Good guess! {guess} is in the word.")
        guessed = True
            for g in self.word:
                if g == guess:
                    guess_index = self.word.find(guess)
                    self.word_guessed[guess_index] = guess
            self.num_letters -= 1
            print(f"Your progress so far: {self.word_guessed}.")

    else:
        self.num_lives -= 1
        print(f"Sorry. {guess} is not in the word. Try again.")
        print(f"You have {self.num_lives} lives left.")
        print(f"Your progress so far: {self.word_guessed}.")

有什么想法可以确保每个实例都被替换。我想我需要某种形式的 while 循环，但不确定条件应该是什么。

我尝试了不同的 while 循环，但找不到一个可以工作的。如果被猜的词是 apple，我最终会得到 [a,p,_,l,e]

要替换单词中猜测的字母的所有实例，您不需要 while 循环。您可以继续使用 for 循环，但需要调整更新 word_guessed 列表的方式。

目前，您正在查找第一次出现的猜测字母的索引并替换它，但您需要查找所有出现的字母并替换它们。 试试这个：

class HangmanGame:
    def __init__(self, word):
        self.word = word
        self.word_guessed = ['_' for _ in word]
        self.num_letters = len(word)
        self.num_lives = 6

    def guess_letter(self, guess):
        if guess in self.word:
            print(f"Good guess! {guess} is in the word.")
            guessed = True
            for i in range(len(self.word)):
                if self.word[i] == guess:
                    self.word_guessed[i] = guess
            self.num_letters -= 1
            print(f"Your progress so far: {' '.join(self.word_guessed)}.")

        else:
            self.num_lives -= 1
            print(f"Sorry. {guess} is not in the word. Try again.")
            print(f"You have {self.num_lives} lives left.")
            print(f"Your progress so far: {' '.join(self.word_guessed)}.")


# Example usage:
game = HangmanGame("hangman")
game.guess_letter("a")

输出：

Good guess! a is in the word.
Your progress so far: _ a _ _ _ a _.

你不需要类来实现这个猜谜游戏

def guess_me(secret='Replace each item in the list', moves=5):
    guess  = ''.join(i if i.isspace() else '_' for i in secret)
    print(guess)
    while moves > 0:
        x = input(f'moves {moves} enter letter ')
        if x in secret:
            guess = ''.join(i if i==x else guess[n] for n,i in enumerate(s))
            print(guess)
        else:
            moves -= 1
            print('nope')
        if guess == secret: return True
    return False
