Question

我有三个清单：＆＃34;产品＆＃34;，＆＃34;价格＆＃34;和＆＃34;项目编号＆＃34;。当用户输入被添加到这些列表中时，我如何让Python创建一个关联，让我们说＆＃34;产品6，价格6和项目编号6＆＃34;？

我希望能够看到的是，当用户从表中选择一个项目编号时，它会被存储，而项目编号实际上知道为自己分配产品的价值和价格。

Jay's House of Rip-Offs


Item Number     |Item Name       |Price           
--------------------------------------------------
1               |Notebook        |4.99            
2               |Atari           |99.99           
3               |TrapperKeeper   |89.99           
4               |Jeans           |3.99            
5               |Insects         |2.99            
6               |Harbormaster    |299.99          
7               |Lobotomy        |19.99           
8               |PunkRock        |3.99            
9               |HorseFeathers   |4.99            
10              |Pants           |2.99            
11              |Plants          |119.99          
12              |Salami          |1.99            

Order products [Y / N]?:

这是我的代码，我真的不知道该怎么做才能让它发挥作用。我需要用户输入来存储＆＃39;订单＆＃39;和＆＃39;数量＆＃39;。此外，名称和地址输入的输入需要存储在上面的相应列表中。

products = ['Notebook', 'Atari', 'TrapperKeeper', 'Jeans', 'Insects', 
'Harbormaster', 'Lobotomy', 'PunkRock', 'HorseFeathers', 'Pants', 
'Plants', 'Salami']
prices = ['4.99', '99.99', '89.99', '3.99', '2.99', '299.99', '19.99', 
'3.99', '4.99', '2.99', '119.99', '1.99']
item_nums = [1, 2, 3, 4, 5, 6, 7, 8 ,9, 10, 11, 12]
orders = []
quantity = []
response = ''
cust_name = ''
street = ''
city = ''
state = ''
zipcode = 0
order_total = 0
order_summary = ''

print("Jay's House of Rip-Offs\n\n")
titles = ('Item Number', 'Item Name', 'Price')
data = [titles] + list(zip(item_nums, products, prices))

for i, d in enumerate(data):
    line = '|'.join(str(x).ljust(16) for x in d)
    print(line)
    if i == 0:
        print('-' * len(line))

while str(input("Order products [Y / N]?: ")) != 'N':
    item_nums = input("Enter an item number: ")
    orders.append(item_nums)
    quantity = input("How many? ")

    if len(item_nums) == 0:
        print("Thank you for browsing.")
    else:
        cust_name = input("Enter name: ")
        street = input("Enter street address: ")
        city = input("Enter city or town name: ")
        state = input("Enter state or province: ")
        zipcode = input("Enter zipcode: ")

如果您不想使用类如何使用嵌套字典来存储数据？可能的实现可能如下所示：

products = {1: {"Type": "Notebook", "Price": 4.99}, 2: {"Type": 
"Atari", "Price": 99.99}} 

print(products[1]) 

> {'Type': 'Notebook', 'Price': 4.99}

将值分配给多个相关列表中的列表项
