1. 项目

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。

2. 代码

class Restaurant():
    def __init__(self, restaurant_name, cuisine_type):
        self.restaurant_name = restaurant_name
        self.cuisine_type = cuisine_type
        self.number_served = 0  # 添加属性，设置默认值为0

    def describle_restaurant(self):
        print(self.restaurant_name, self.cuisine_type)

    def open_restaurant(self):
        print("Now is opening...")

    def read_restaurant(self):
        print("The restaurant have " + str(self.number_served) + ' people eating.')

    def set_number_served(self, member):    # 添加方法，设置就餐人数
        self.number_served = member

    def increment_number_served(self, members): # 添加方法，设置递增人数
        self.number_served += members


class IceCreamStand(Restaurant):
    def __init__(self, restaurant_name, cuisine_type):
        super().__init__(restaurant_name, cuisine_type)
        self.flavors = []

    def ShowIceCream(self):
        for flavor in self.flavors:
            print(flavor)

ICS = IceCreamStand('Haagen-Dazs', 'IceCream')
ICS.flavors = ['TiLaMiSu', 'AiQingHaiZhiZhou', 'HeiSenLinLianQu']
ICS.ShowIceCream()
