Python Hangman -循环

Question

我正在尝试写一个函数，用来扮演刽子手，一切都很完美，除了这个函数不知道什么时候游戏赢了。

这是我修改过的代码

def hangman():
    word = choose_word(wordlist)
    guessed_word = len(word)*['_']
    guesses = 10
    available_letters = "abcdefghijklmnopqrstuvwxyz"
    guessed_letters = ""
    letters_correct = 0
    print "Welcome to the game, Hangman!"
    print "I am thinking of a word that is", len(word), "letters long."
    print "Available letters:", available_letters
    print "You have", guesses, "guesses."
    while letters_correct != len(word):
        guess = raw_input("enter your guess:")
        if len(guess)==1 and guess.isalpha():
            if guessed_letters.find(guess) != -1:
                print "You already picked", guess
            else:
                guessed_letters = guessed_letters + guess
                index1 = word.find(guess)
                if  index1 == -1:
                    print "The letter",guess,"is not in the word", ' '.join(guessed_word)
                    guesses = guesses - 1
                    print "You have", guesses, "guesses left."
                    if guesses == 0:
                        return "You are out of guesses. You lose. The word was "+ word + "."
                    available_letters = available_letters.replace(guess, '')
                    print "Available letters:", available_letters
                else:
                    letters_correct = letters_correct + word.count(guess)
                    print"The letter", guess, "is in the word."
                    for i in range(len(word)):
                        if guess == word[i]:
                            guessed_word[i] = guess
                            print ' '.join(guessed_word)
                            if letters_correct != len(word):
                                print "You have", guesses, "guesses left."
                                available_letters = available_letters.replace(guess, '')
                                print "Available letters:", available_letters
                            elif guesses <= 0:
                                return "You are out of guesses. You lose. The word was "+ word + "."
        else:
            print "Please guess a single letter in the alphabet."
    if letters_correct == len(word):
        return "Congratualations! You figured out that the word is "+ word

挂人游戏循环不终止问题的原因是游戏同时循环检查的letters_correct计数器变量。

while letters_correct != len(word):

假设这个词是香蕉，我猜字母a

代码中处理正确猜测的分支以以下行开始：

letters_correct = letters_correct + 1

在我的单词、香蕉、和a中，letters_correct变量应该增加三次。现在，如果我猜n，letters_correct应该增加两次。

在当前的实现猜测中，我按顺序只增加letters_correct两次(2)，而应该是5。因此，当增加letters_count增量时，猜测次数出现在word中。

letters_count = letters_count + word.count(guess)

这样，在游戏循环中，检查letters_count变量实际上可以达到单词的长度。

你有没有考虑过你的单词有多个字母的情况？

目前，如果用户猜测正确，则只增加一次letters_correct。如果每次增加一次正确字母的数量，它就会工作。
