如何在python 2.7.4中随机化字典？

Question

我对编码有点新意，但这个问题一直困扰着我。我试图将字典随机化，以便每次玩游戏时我都会得到一个不同的场景。然后我希望它返回那个场景，以便我可以播放那个场景。这是脚本：

from sys import exit
import time
import random
#import another file here to use in this

class Scene(object):
    def enter(self):
        print "Not yet configured."



class Start():

    def start(self):
        print "Hello. How are you? You are about to play a game that is set in a crazy world."
        print "We are creating your profile right now."
        epic = raw_input("Enter your name here: ")
        print "Hello, %s." % epic
        print "You are being transported to a randomly generated world. Try to survive as long as possible."
        print "Here's some advice, %s: Don't die. Make the right choice. Be careful." % epic
        print "The rules will be shown to you soon."
        print "LOADING..."
        time.sleep(1)
        return Rules().rules()

class Rules(Scene):

    def rules(self):
        print ""
        print "-------------"
        print ""
        print "These are the rules:"
        print "1: Be a good sport. This game takes skill and memory to be able to win, so try your best to succeed."
        print "2: Every time you die, you do not get to respawn, so you will be prompted to either just not play anymore"
        print "or play again. If you decide to play again, you will most likely be on a new world with a new puzzles."
        print "3: Finally, have fun. Hopefully this game brings you joy, so have a great time playing it."
        return random.choice(Map.shuffler.keys())

class BoilerRoom(Scene):

    def boiler_room(self):
        print "You are in the boiler room."

class Kitchen(Scene):

    def kitchen(self):
        print "You are in the kitchen."

class Pool(Scene):

    def pool(self):
        print "You are in the pool."

class TennisCourts():

    def tennis_courts(self):
        print "You are in the tennis courts."

class SoccerField():

    def soccer_field(self):
        print "You are on the soccer field."

class Map(object):

    scenes = {
        Rules(): 'rules',
        BoilerRoom(): 'boiler_room',
        Kitchen(): 'kitchen',
        Pool(): 'pool',
        TennisCourts(): 'tennis_courts',
        SoccerField(): 'soccer_field'
    }

    shuffler = {
        BoilerRoom(): 'boiler_room',
        Kitchen(): 'kitchen',
        Pool(): 'pool',
        TennisCourts(): 'tennis_courts',
        SoccerField(): 'soccer_field'
    }


Start().start()
