我正在猜python中的单词游戏。这是我的学校项目。我快完成了，我只有一件事有问题。我无法弄清楚如何掩盖一个单词。例如，如果单词是monkey，则程序应显示------并且当用户猜出一个字母时，假设为k，程序应该显示--- k -
不幸的是我必须以某种方式编写代码。我应该有一个主函数，它只会调用其他函数来完成所有的工作（比如会询问用户输入一个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。
该函数名为maskWord(state, word, guess)。我必须保留这些变量，但它们将被传递给函数。 state是被屏蔽的单词（例如.------），word是要猜的单词（例如猴子），guess是用户猜到的字母。一旦函数更新了被屏蔽的单词，它就会返回state。另一个规则是我无法创建全局变量。传递的变量是必须使用的变量。
这就是我所拥有的：
def maskWord(state, word, guess)
guessed = []
guessed.append(guess)
for guess in word:
if guess in guessed:
state += guess
else: state += "-"
return state
它确实不起作用。因为调用此函数的主函数是while循环，所以每次guessed变为空字符串。
如果有人可以帮助我，我会非常感激。我知道必须只使用变量来编写这个函数，因为我的老师只允许使用它们。

修正了我的回答以反映评论，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，扩展了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
