Python实现的简单hangman游戏实例

本文实例讲述了Python实现的简单hangman游戏。分享给大家供大家参考。具体如下：

#!/usr/bin/env python
import random
import cPickle
class Hangman(object):
 '''A simple hangman game that tries to improve your vocabulary a bit '''
 def __init__(self):
   # the variables used, this is not necessary
   self.dumpfile = ''    #the dictionary file
   self.dictionary = {}   #the pickled dict
   self.words = []     #list of words used
   self.secret_word = ''  #the 'key'
   self.length = 0     #length of the 'key'
   self.keys = []      #inputs that match the 'key'
   self.used_keys = []   #keys that are already used
   self.guess = ''     #player's guess
   self.mistakes = 0    #number of incorrect inputs
   return self.load_dict()
 #insert some random hints for the player
 def insert_random(self, length):
   randint = random.randint
   # 3 hints
   if length >= 7: hint = 3
   else: hint = 1
   for x in xrange(hint):
       a = randint(1, length - 1)

   if self.guess in self.secret_word:
     indexes = [i for i, item in enumerate(self.secret_word) if item == self.guess]
     for index in indexes:
       self.keys[index] = self.guess
       self.used_keys.append(self.guess)

   #if the guessed letter didn't match
   else:
     self.used_keys.append(self.guess)
     self.mistakes += 1
     print "used letters ",set(self.used_keys),'\n'
 # load the pickled word dictionary and unpickle them  
 def load_dict(self):
   try :
     self.dumpfile = open("~/python/hangman/wordsdict.pkl", "r")
   except IOError:
     print "Couldn't find the file 'wordsdict.pkl'"
     quit()
   self.dictionary = cPickle.load(self.dumpfile)
   self.words = self.dictionary.keys()
   self.dumpfile.close()
   return self.prepare_word()

   self.keys = ['_' for x in xrange(self.length)]
   self.insert_random(self.length)
   return self.ask()
 #display the challenge
 def ask(self):
   print ' '.join(self.keys), ":", self.dictionary[self.secret_word]
   print
   return self.input_loop()
 #take input from the player
 def input_loop(self):
   #four self.mistakes are allowed
   chances = len(set(self.secret_word)) + 4    
   while chances != 0 and self.mistakes < 5:
     try:
       self.guess = raw_input("> ")
     except EOFError:
       exit(1)
     self.test_input()
     print ' '.join(self.keys)
     if '_' not in self.keys:
       print 'well done!'
       break
     chances -= 1
   if self.mistakes > 4: print 'the word was', ''.join(self.secret_word).upper()
   return self.quit_message()
 def quit_message(self):
   print "\n"
   print "Press 'c' to continue, or any other key to quit the game. "
   print "You can always quit the game by pressing 'Ctrl+D'"
   try:
     command = raw_input('> ')
     if command == 'c': return self.__init__() #loopback
     else : exit(0)
   except EOFError: exit(1)
if __name__ == '__main__':
 game = Hangman()
 game.__init__()
