笨办法学python 习题42 加分练习

3、创建一个新版本，里边使用两个 class，其中一个是 Map ，另一个是 Engine 。提示: 把 play 放到 Engine 里面。、

#coding=utf-8
from sys import exit
from random import randint

class Map(object):
    def __init__(self):       
        self.quips = ["You died. You kinda suck at this.","Your mom would be proud. If she were smarter.","Such a luser.","I hava a small puppy that‘s better at this."]

    def death(self):
        print self.quips[randint(0,len(self.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:
            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
            guesses = 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:
            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)

class Engine(Map):
    def __init__(self,start):
        self.start = start
  
    def play(self):        
        next = self.start
        while True:
            print "\n-----------"
            room = getattr(self,next)
            next = room()

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