Shopping List Price Calculation

Given two arrays: one containing items and their prices, and another containing item discounts. Additionally, a shopping list with potential duplicate items is provided. Write a program to calculate the discounted total price for each item in the shopping list and output in the format <item, price, discounted_total_price>. Note: the program should inherit from an abstract class, and the constructor needs to be implemented by you. Example Input items = [('apple', 100), ('banana', 150), ('cookie', 200)] discounts = [('apple', 0.1), ('cookie', 0.2)] shopping_list = ['apple', 'banana', 'apple', 'cookie'] Output [('apple', 100, 90.0), ('banana', 150, 150.0), ('apple', 100, 90.0), ('cookie', 200, 160.0)]
