带输入的for循环 - PYTHON

Question

我需要用Python编写一个披萨订购系统。在我的程序中，有一部分需要询问用户想要多少个披萨，然后让他们从披萨列表中选择他们想要的种类，用户需要选择不同的披萨。我想用一个循环来重复这个输入问题，次数就是用户说他们想要多少个披萨。

到目前为止，我的代码有两个部分。我的第一个输入问题是：

pizza_number= int(input("How many Pizzas do you want? (MAX 5): "))

还有披萨的列表：

PIZZA_LIST=["Tandoori chicken: $8.50", "Prawn: $8.50", "Ham and cheese: $8.50", "Pepperoni: $8.50", "Hawaiian: $8.50","Beef and onion: $8.50","Meat lovers: $8.50", "Satay chicken: $13.50", "Apricot chicken: $13.50", "Supreme cheese:13.50", "Italian beef: $13.50", "Mediterraneo: $13.50"]
for index in range(0, len(PIZZA_LIST)):
    print(index, PIZZA_LIST[index])

菜单会展示给用户，每个披萨旁边会有一个数字，当他们说出想要哪个披萨时，就输入对应的数字（例如，1 = 虾披萨，2 = 火腿奶酪披萨等等）。

我该如何编写这个循环呢？

你已经有了大部分的组件。下面是如何把它们组合在一起的方法。

pizza_number= int(input("How many Pizzas do you want? (MAX 5): "))
PIZZA_LIST=["Tandoori chicken: $8.50", "Prawn: $8.50", "Ham and cheese: $8.50", "Pepperoni: $8.50", "Hawaiian: $8.50","Beef and onion: $8.50","Meat lovers: $8.50", "Satay chicken: $13.50", "Apricot chicken: $13.50", "Supreme cheese:13.50", "Italian beef: $13.50", "Mediterraneo: $13.50"]
pizzas = []
for i in range(pizza_number):
    for index in range(0, len(PIZZA_LIST)):
        print(index, PIZZA_LIST[index])
    pizza = int(input("Select a pizza: "))
    pizzas.append(pizza)
