• 9.1餐馆。

class Restaurant():
    def __init__(self,name,cuisine_type):
        self.restaurant_name = name
        self.c_type = cuisine_type
    def describe_restaurant(self):
        print(self.restaurant_name+', '+self.c_type)
    def open_restuarant(self):
        print(self.restaurant_name+" is in work!")
rest = Restaurant("MacDonald","Fast-Food")
rest.describe_restaurant()
rest.open_restuarant()

• 9.2三家餐馆。(以9.1创建的类为基础)

ck = Restaurant("Cake","Cakes and Pastries")
mc = Restaurant("MacDonald","Fast-Food")
kfc = Restaurant("KFC","Fast-Food")
ck.describe_restaurant()
mc.describe_restaurant()
kfc.describe_restaurant()

• 9.4 就餐人数。

class Restaurant():
    def __init__(self,name,cuisine_type):
        self.restaurant_name = name
        self.c_type = cuisine_type
        self.number_served = 0
    def describe_restaurant(self):
        print(self.restaurant_name+', '+self.c_type)
    def open_restuarant(self):
        print(self.restaurant_name+" is in work!")
    def set_number_served(self,num):
        self.number_served = num
    def increment_number_served(self,add_number):
        self.number_served += add_number

• 9.6 冰淇淋小店。(以9.4的Restaurant类为基础)

        self.flavors = flavours
    def show_flavors(self):
        print(self.restaurant_name+" has following different icecream:")
        print(self.flavors)
ice = IceCreamStand("冰淇淋小店","IceCream",["玫瑰卷","彩绘","富士山雪顶系列","花式冰淇淋系列","..."])
ice.show_flavors()
