print("\n")

class Restaurant_serve():
    def __init__(self, restaurant_name, cuisine_type):
        self.restaurant_name = restaurant_name
        self.cuisine_type = cuisine_type
        self.number_served = 0

    def increment_number_served(self):
        self.number_served += 1

nice_place.set_number_served(500)

print("\n")

class IceCreamStand(Restaurant_serve):
    def __init__(self, restaurant_name, cuisine_type, flavors):
        super().__init__(restaurant_name, cuisine_type)
        self.flavors = flavors
    
    def show_flavors(self):
        print("The flavors are: ")
        for flavor in self.flavors:

from random import randint
class Die():
    def __init__(self, side=6):
        self.side = side
    
    def roll_die(self):
        x = randint(1, self.side)
        print("  " + str(x))
for side in [6, 10, 20]:
    die = Die(side)
    print("Side: " + str(side))
    for i in range(1, 11):
        die.roll_die()

输出如下：

KFC with fired chicken
Restaurant is openning


Number reserved is 500
Now, number reserved is 501


The flavors are: 
	white
	black
