python编程从入门到实践：while循环练习：披萨配料 ```python

burdening = 'nPlease tell me some burdenings
(Enter "quit" when you are finished.): '
pizzas = []  #创建一个披萨的空列表，里面可填充while循环里的配料
while True:
    pizza = input(burdening)

    if pizza == 'quit':
        break
    else: 
        print('n我们会在披萨里添加{}!'.format(pizza.title()))
        pizzas.append(pizza)
        print(pizzas)
print(f'你选了{pizzas}口味的披萨！')  #打印出来while循环里添加进去的所有配料的披萨
