Python 3

You are given a complex list of n products, each with a names, prices, and weights. Find out how many duplicate products are present within the list. Duplicate products contain identical parameters for all fields in the list (i.e. names, prices, and weights). Example: There are n = 5 products with attributes listed in three arrays, aligned by index. names = [hat, jacket, shoe, shoe, shoe] prices = [2, 3, 1, 2, 1] weights = [2, 5, 1, 1, 1] A complete item description for item 0: (names[0], prices[0], weights[0]) is (hat, 2, 2) Price Weight 2 2 jacket 3 5 shoe 1 1 shoe 2 1 shoe 1 1 Name hat The first two items are unique. The two shoes at indices 2 and 4 are equal in all
