因此，作为MIT ocw问题集的一部分，我正在尝试为python上的hangman游戏编写代码。这是迄今为止的代码：
WORDLIST_FILENAME = "words.txt"
def load_words ():
print "Loading word list from file..."
inFile = open ( WORDLIST_FILENAME, ' r ' , 0 )
line=inFile.readline ( )
line = str(line)
wordlist = str.split(line)
print " ", len(wordlist), "words loaded"
return wordlist
def choose_word(wordlist):
return random.choice(wordlist)
wordlist = [e [1:-4] for e in wordlist ]
wordlist = [str.lower (e) for e in wordlist ]
def correct(word,guess):
wordspace = ["_ "] * len(word)
occur = word.count(guess)
print "Occurences are", occur
word = list(word)
while occur > 0:
print "First index is", word.index(guess)
wordspace[word.index(guess)] = guess
print wordspace
print word
occur -=1
print ', '.join(wordspace)
return word
def hangman():
word = choose_word(wordlist)
print "Welcome to Hangman, the interactive game!"
print "I am thinking of a word", len(word), "letters long..."
word = list(word)
wordspace = ["_ "] * len(word)
print ', '.join(wordspace)
guessnumber = 8
while guessnumber >= 1:
guess = str(raw_input("Please make a guess..."))
guessnumber -= 1
if guess in word:
print "Yoy have guessed correctly!"
correct(word,guess)
else:
print "Wrong!"
print "You have", guessnumber, "guesses left."
现在您已经看过代码，让我告诉您问题：
总的来说，这段代码有潜力，但我遇到了这个困难：
正确的函数在空格中打印单词，除了正确猜出的字母，但未来的迭代不会保留。
例如，假设这个词是梯形图。如果玩家输入“d”，则可以显示正确的功能：
_ _ d d _ _
哪个好。但假设玩家接下来输入“r”。代码原样可以显示：
_ _ _ _ _ r
但不是：
_ _ d d _ r
这就是我想要的。
另外，一旦完全猜到，我怎么能让游戏过期并打印整个单词？也许我应该在某个地方放置休息条件，但在哪里？
我该如何解决这个问题？
感谢和抱歉这个冗长的问题。

您需要存储有关已在某处猜到的字母的信息。在这种情况下，我建议事先制作一个空白列表并使用它。
guessedlist = []
def correct(word,guess):
global guessedlist # You need to make guessedlist a global variable to have an access
guessedlist = guessedlist + [guess]
wordspace = []
for i in word:
if i in guessedlist:
wordspace = wordspace + [i + ' ']
else:
wordspace = wordspace +['_ ']
# Now wordspace is an ordered list with mix of '_ '(unguessed) and guessed letters.
# I hope this might suit your needs

作为我的python课程的一部分，我不得不使用MIT网站做同样的问题。我用以下代码完成了课程。
import random
import string
import re
WORDLIST_FILENAME = "words.txt"

return wordlist

我希望这会有所帮助。如果它确实请投票。谢谢！
