class Restaurant():

        self.restaurant_name = restaurant_name
        self.cuisine_type = cuisine_type
        self.number_served = 0

        print("冰淇淋口味有以下几种：" + str(self.flavors))


get_flavors = IceCreamStand('幸福餐厅','中餐')
get_flavors.IceCream_flavors()

报以下错误：

get_flavors = IceCreamStand('幸福餐厅','中餐')

super().__init__(self,restaurant_name,cuisine_type)

TypeError: __init__() takes 3 positional arguments but 4 were given

问题是父类可接受的属性变量有3个，但是提供了4个；

解决方法：super().__init__(self,restaurant_name,cuisine_type)改为super().__init__(restaurant_name,cuisine_type)；集成父类super的init参数不需要self；
