Using a list as an index for another list python-CodePudding

I am trying to create an online shopping cart system in python to understand list better but have come across some struggles.

I am having difficulties with displaying information using a list. I have already created a list where the person writes in the product the code into an empty list as shown below.

else:
    code_input.append(i)
    quan_input.append(s)
code_inputed.append(code_input)
quan_inputed.append(quan_input)

I want to use the list with the product codes to find the correlating name and price by using trying to use the code_input list as an index to find the items in the other list.

I have written the simple code to try to find if it works but it comes up with TypeError: list indices must be integers or slices, not list

The code

def display():
    index = code_inputed
    for i in code_inputed: # and index in range(len(productList)):
        print(index)
        print(productList[index], quan_inputed[index])

Any help would be greatly appreciated and I'm sorry if none of this makes any sense I am only new.

Thank you

It is a bit unclear what you want, but do you perhaps mean:

def display():
index = code_inputed
for i in code_inputed: # and index in range(len(productList)):
    print(i) #CHANGED TO i!
    print(productList[i], quan_inputed[i])

CodePudding user response：

def display():
index = code_inputed
for i in code_inputed: # and index in range(len(productList)):
    print(i)
    print(productList[i], quan_inputed[i])

where "i" represent an item in the code_inputed list and item in quan_inputed list

I think what you want to achieve is to tie product code for the actual product. Maybe consider using dict?

myShop= [
    {
        "productName": "Table",
        "color": "Red",
        "price": "79",
        "productCode": "7546374"
    },

    {
        "productName": "Smart Tv",
        "color": "White",
        "price": "159",
        "productCode": "7546375"
    }
]

    # Print products
def print_products():
    
    for product in myShop:
        print(
            "[ "   product["productName"]   " ]",
            "[ "   product["color"]   " ]",
            "[ "   product["price"]   " ]",
            "[ "   product["productCode"]   " ]",
                
            sep = " - ")
    
    
print_products()
