如何在課堂上使用字典？它顯示字典沒有定義

Question

我確實定義了字典，但它一直說字典「房間」沒有定義。

首先，我認爲這是因爲字典是在課外，但是當我把它放在課堂上時，它仍然顯示相同的信息。

那麼我想知道如何在課堂上參考一本字典？ 感謝第一個答案，我已經試過self.ROOMS，它的工作。但是如果我有很多字母，我必須把它們全部放在方法init ??但推薦在「學習python的難題」中，我們最好不要把這麼多的東西放在init

代碼附在這裏，而不相關的部分已經最小化了。

from sys import exit 
from random import randint 


class Game(object): 


    def __init__ (self, start): 
     self.quips = ['You died.you kinda suck at this.', 'Nice job, you died...jackass.', 
      "Such a luser.", 
      'I have a small puppy that\'s bettr at this.'] 
     self.start = start 

    def play (self): 
     next = self.start 

     while True: 
      print "\n--------" 
      room = ROOMS[next] 
      next = room() 

    def death(self): 

     print self.quips[randint(0,len(quips)-1)] 
     exit(1) 


    def central_corridor(self): 

     action = raw_input(">") 

     if action == "shoot!": 

      return 'death' 

     elif action == "dodge!": 

      return 'death' 

     elif action == "tell a joke": 

      return 'laser_weapon_armory' 

     else : 
      print "DOES NOT COMPUTE!" 
      return 'central_corridor' 



    def laser_weapon_armory(self): 

     code = "%d%d%d" %(randint(1,9), randint(1,9), randint(1,9)) 
     guess = raw_input("[keypad]>") 
     guesses = 0 

     while guess != code and guesses < 10: 
      print "BZZZZEDDD!" 
      guesses += 1 
      guess = raw_input("[keypad]>") 

     if guess == code: 

      return 'the_bridge' 
     else: 

      return 'death' 

    def the_bridge(self): 

     action = raw_input("> ") 

     if action == "throw the bomb": 

      return 'death' 

     elif action == "slowly place the bomb": 

      return 'escape_pod' 
     else: 
      print "DOES NOT COMPUTE!" 
      return "the_bridge" 

    def escape_pod(self): 


     good_pod = randint(1,5) 
     guess = raw_input("[pod#]> ") 


     if int(guess) != good_pod: 

      return 'death' 

     else: 

      exit(0) 


    ROOMS = { 
       'death' : death, 
       'central_corridor' : central_corridor, 
       'laser_weapon_armory' : laser_weapon_armory, 
       'the_bridge' : the_bridge, 
       'escape_pod' : escape_pod 
     } 


a_game = Game("central_corridor") 
a_game.play()

可以的ROOMS定義移動到你的類的__init__方法，後來將其稱爲self.ROOMS也預先考慮到self.函數名....

class Game(object): 


    def __init__ (self, start): 
     self.quips = ['You died.you kinda suck at this.', 'Nice job, you died...jackass.', 
      "Such a luser.", 
      'I have a small puppy that\'s bettr at this.'] 
     self.start = start 


     self.ROOMS = { 
      'death' : self.death, 
      'central_corridor' : self.central_corridor, 
      'laser_weapon_armory' : self.laser_weapon_armory, 
      'the_bridge' : self.the_bridge, 
      'escape_pod' : self.escape_pod 
     } 

    def play (self): 
     next = self.start 

     while True: 
      print "\n--------" 
      room = self.ROOMS[next] 
      next = room()
