Python编程从入门到实践 9-6冰淇淋小店

   冰淇淋小店是一种特殊的餐馆。编写一个名为IceCreamStand 的类，让它继承你为完成练习9-1或练习9-4而编写的Restaurant 类。这两个版 本的Restaurant 类都可以，挑选你更喜欢的那个即可。添加一个名为flavors 的属性，用于存储一个由各种口味的冰淇淋组成的列表。编写一个显示这些冰淇淋 的方法。创建一个IceCreamStand 实例，并调用这个方法。

restaurant.describe_restaurant()
restaurant.open_restaurant()
restaurant.increment_number_served(100)
restaurant.set_number_served(40)
restaurant.read_restaurant()ice_cream=IceCreamStand('HunberKing','fast food')
ice_cream.describe_ice()

结果为：
