Question

Products = {
    "BUTTER": (4.50,False),
    "BREAD": (2.70,False),
    "BUTTON MUSHROOMS": (1.15,False),
    "BAKING BEAN": (1.35,True),

    print("Name".ljust(padding), f'{"Price":>12}', f'{"Membership Applicable":>25}')

    for name, (price, val) in Products.items():

        print(name.ljust(padding), f"{price:>10}",f"{str(val):>18}")

def addItem():
    itemlist()
    getselection = input(
        "Enter an item from the list above that u would like to add to cart :"
    )
    quantity = int(input("Enter how many of this item u would like to add to cart: "))
    if quantity < 0:
        print("Invalid quantity input")

    elif getselection.upper() in Products:
        shoppingCart[getselection.upper()] = quantity
        print("\n", quantity, "of", getselection, "has been added to cart !\n",)

    else:
        print("Item not found")

addItem()
