我正在用python写一个猜词游戏。这是我的学校项目。我快完成了，我只有一件事有问题。我不知道如何掩盖一个词。例如，如果单词是猴子，程序应该显示 ------ 并且当用户猜一个字母，比如说 k，程序应该显示 ---k--

不幸的是，我必须以某种方式编写代码。我应该有一个 main 函数，它只会调用其他可以完成所有工作的函数（比如会要求用户输入字母或检查猜测的单词是否正确的函数）。我已经完成了除了这个屏蔽功能之外的所有功能。

该函数被调用maskWord(state, word, guess)。我必须保留这些变量，但它们将被传递给函数。state是被掩码的单词（例如.------），word是要猜测的单词（例如猴子），并且guess是用户猜测的字母。一旦函数更新了掩码单词，它应该返回state. 另一个规则是我不能创建全局变量。传递的变量是必须使用的变量。

这是我所拥有的：

def maskWord(state, word, guess)
  guessed = []
  guessed.append(guess)
  for guess in word:
    if guess in guessed:
      state += guess
    else: state += "-"
  return state

它真的不起作用。因为我调用这个函数的main函数是一个while循环，所以每次都guessed变成一个空字符串。

如果有人可以帮助我，我将不胜感激。我知道必须可以只使用变量来编写这个函数，因为我的老师只允许使用这些变量。

修复了我的答案以反映评论，它比kjtl的答案要短一些。但它基于相同的概念，通过使用状态......好吧，当前状态:)

def maskWord(state, word, guess):
    state = list(state)
    for i in range(len(word)):
        if word[i] == guess:
             state[i] = guess
    return "".join(state)


# Lets test if it works..:
word = "electricity"
state = "-" * len(word)
tries = 0

play = True
while play:
    if tries == len(word)*2: 
        print "Fail..."; 
        play = False
    guess = raw_input("Guess: ")
    tries +=1
    state = maskWord(state, word, guess)
    print state
    if maskWord(state, word, guess) == word:  
        print "WIN, WIN!!"; 
        play = False

通过使用 state 作为有效猜测的容器来扩展 SLACKY 的答案。

def maskWord(state, word, guess):

    result = ''
    guessed = []
    character = ''
    for character in state:
        if not character == '-':
            if not character in guessed:
                guessed.append(character)

    if not guess in guessed:
        guessed.append(guess)

    for guess in word:
        if guess in guessed:
            result += guess
        else: 
            result += "-"

    # for debugging change to if True:
    if False:
        print 'state %s' % state
        print 'word %s' % word
        print 'guess %s' % guess
        print guessed

    return result


# Lets test if it works..:
import sys

word = "electricity"
state = ""
tries = 0

loop = True
while loop:
    if tries == len(word)*3: 
        print "Fail..."
        loop = False
    else:
        guess = raw_input("Guess: ")
        tries +=1
        state = maskWord(state, word, guess)
        print state
        if maskWord(state, word, guess) == word:    
            print "WIN, WIN!!"
            loop = False
