【练习12】面向对象的小练习

动物园里面有10个房间，房间号从1 到10。每个房间里面可能是体重200斤的老虎或者体重100斤的羊。游戏开始后，系统随机在10个房间中放入老虎或者羊。然后随机给出房间号，要求游戏者选择敲门还是喂食。
如果选择喂食：喂老虎应该输入单词 meat，喂羊应该输入单词 grass。喂对了，体重加10斤。喂错了，体重减少10斤
如果选择敲门：敲房间的门，里面的动物会叫，老虎叫会显示 ‘Wow !!’,羊叫会显示 ‘mie~~’。动物每叫一次体重减5斤。
游戏3分钟结束后，显示每个房间的动物和它们的体重。

#老虎类

    animal_name = '老虎'
    def __init__(self,weight = 200):
        self.weight = weight

        if food == 'meat':
            self.weight += 10
            print('投食正确，体重+10')
        else:
            self.weight -= 10
            print('投食错误，体重-10')

    def roar(self):
        print('Wow!!')
        self.weight -= 5

#羊类
class Sheep:
    animal_name = '羊'

    def __init__(self, weight=100):
        self.weight = weight

    def feed(self, food):
        if food == 'grass':

            print('投食正确，体重+10')
        else:
            self.weight -= 10
            print('投食错误，体重-10')

    def roar(self):

    game_room = randint(1,10)  #用于显示房间号
    roomNo = rooms[game_room-1]
    userChose1 = input(f'当前是{game_room}房间,要敲房门吗？[y/n]')

    userChose2 = input(f'请给动物投食: [meat/grass]')
