Problem Statement This assignment asks you to design a simple shopping program. Your program should list 5 items (shoes, bag, iphone, TV and book) and their prices and ask the user to choose one item from the list and then enter the quantity to purchase. Your program calculates the total cost and print it out. The input for item from user should not be case sensitive, i.e., your program should be able to recognize 'shoes, 'Shoes' or 'SHOES. However, if the input is 'shoe' or other item not in the list, your program should stop execution and give out an error message 'Item not found. Input e Item name Quantity Output The total cost if the item is in the list. An error message if the item is not in the list Hint You can use the function lower() to convert item name to lower cases. The lower() function takes a character array and converts every character to lower case. e.g., lower(Shoes')'shoes', lower('SHOES') 'shoes You can use the function error() to stop execution and give out an error message You can use t to introduce tab between item name and its price Sample Outputs& Test Cases Test1 shoes $50 bag $20 iphone$700 TV $700 book $10 Choose an item from the list: bag Enter quantity: 2 Your total is $40.00
