Question

我刚写了一个运行程序来玩 Hangman 游戏，但有一个问题一直困扰着我，我一直没弄明白。

程序正确评估所选字符是否在要猜测的单词中，以及它在单词中的位置（即使该字符出现不止一次）。尽管如此，在玩游戏时，需要多转一圈来评估你是否完全猜对了这个词，或者你是否已经没有生命了。

比如说，你必须猜出单词 'hello'。我希望编程为运行，例如：

第 1 回合：'h'。转弯 2：'e'。转3：'l'。转4：'o'。程序应该在这里停止，但它需要另一个角色（任何）来识别游戏已经完成。

这是我的代码：

def play_game():

    # Pick word randomly from list
    random_num = random.randint(0, (len(words_list) - 1))
    current_word = list(words_list[random_num].upper())
    print(current_word)
    print('The word has', str(len(current_word)), 'characters')

    current_letter = input('Pick a letter: ').upper() #User input
    picked_letters = []
    correct_ones = []
    for i in range(len(current_word)):
        correct_ones.append('_ ')

    lifes = 3
    while lifes != 0:

        # Check if all characters have been already guessed
        if current_word == correct_ones:
            print('You won!')
            break

        # Check if character has already been chosen
        elif current_letter in picked_letters:
            print('You already chose this letter!')
            current_letter = input('Pick another letter: ').upper()
            continue

        # Check if character is in word
        if current_letter in current_word:
            index_list = []
            for i in range(len(current_word)): #Get indexes of character in word
                if current_word[i] == current_letter:
                    index_list.append(i)

            picked_letters.append(current_letter) #Append to keep track of chosen characters         
            for i in index_list:
                correct_ones[i] = current_letter.upper() #Append to correct position

            print('Correct!')
            for i in correct_ones:
                print(i + ' ', end='')
            current_letter = input('Pick another letter: ').upper()

        # Incorrect character
        else:
            picked_letters.append(current_letter)
            lifes -= 1
            print('Incorrect')
            print('You have', str(lifes), 'lifes left')
            current_letter = input('Pick another letter: ').upper()
            continue

如果您在我的代码中看到任何不好的做法，请随时告诉我！

Answer 1

您在循环结束时要求用户输入。所以当你输入最后一个正确的字符时，你再次要求用户输入：

print('Correct!')
for i in correct_ones:
    print(i + ' ', end='')
current_letter = input('Pick another letter: ').upper()

要解决此问题，您可以将在循环开始时所做的检查移至此处。因为在游戏开始时，没有给出任何输入，所以永远不会正确猜出这个词（除非真正的词是空的，但这种情况不应该发生！）。而且因为只有猜对了一个字符才能让你获胜，所以在那里检查它是有意义的。希望这对您有所帮助，玩得开心:)

我对您的代码进行了一些更改。现在它按预期工作了。

def play_game():

    # Pick word randomly from list
    random_num = random.randint(0, (len(words_list) - 1))
    current_word = list(words_list[random_num].upper())
    print(current_word)
    print('The word has', str(len(current_word)), 'characters')

    picked_letters = []
    correct_ones = []
    for i in range(len(current_word)):
        correct_ones.append('_ ')

    lifes = 3
    while lifes != 0:

        # Check if all characters have been already guessed
        if current_word == correct_ones:
            print('You won!')
            break

        current_letter = input('Pick a letter: ').upper()

        # Check if character has already been chosen
        if current_letter in picked_letters:
            print('You already chose this letter!')
            continue

        # Check if character is in word
        if current_letter in current_word:
            index_list = []
            for i in range(len(current_word)):  # Get indexes of character in word
                if current_word[i] == current_letter:
                    index_list.append(i)

            picked_letters.append(current_letter)  # Append to keep track of chosen characters
            for i in index_list:
                correct_ones[i] = current_letter.upper()  # Append to correct position

            print('Correct!')
            for i in correct_ones:
                print(i + ' ', end='')

        # Incorrect character
        else:
            picked_letters.append(current_letter)
            lifes -= 1
            print('Incorrect')
            print('You have', str(lifes), 'lifes left')
            continue

这是一个快速循环，可以添加您的猜测并将您的单词变成“-”。

while tries > 0:
    hiddenphrase = ""
    for char in word:
        if char in guessed:
            hiddenphrase = hiddenphrase + char
        elif char in letters:
            hiddenphrase = hiddenphrase + "-"
        else:
            hiddenphrase = hiddenphrase + char
