Python - Hangman

Question

我刚刚写了一个程序来玩Hangman游戏，但是有一个问题困扰着我，我一直没能弄清楚。

程序正确地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，在玩游戏的时候，不管你完全猜到了这个词，还是你已经没有生命了，你都需要比需要多一个回合。

比如说，你必须猜到“你好”这个词。我希望程序运行的方式如下：

转1：'h‘。转2: e。第三圈：“我”。转4圈:O。程序应该停止在这里，但它需要另一个字符(任何)，以承认游戏已经完成。

这是我的密码：

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实践，请告诉我！

提前感谢！

Answer 1

您在循环结束时向用户请求输入。因此，当您输入最后一个正确的字符时，再次请求用户输入：

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

要解决这个问题，您可以将循环开始时所做的检查移到那里。因为在游戏开始时，没有输入，所以单词永远不应该被正确地猜测(除非真正的单词是空的，但不应该这样！)因为只有猜测一个正确的字符才能让你获胜，所以在那里检查它是有意义的。希望这有帮助，玩得开心点:)

我对您的代码做了一些修改。现在，它如预期的那样工作。

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

下面是一个快速循环，它将添加您的猜测并将您的单词添加到"-“中。

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
