pty dictionary. If the file does not 8. Cash Register This exercise assumes you have created the Retail Item class for Programming Exer- cise 5. Create a CashRegister class that can be used with the Retail Item class. The CashRegister class should be able to internally keep a list of Retail Item objects. The class should have the following methods: • A method named purchase_item that accepts a Retail Item object as an argument. Each time the purchase_item method is called, the Retail Item object that is passed as an argument should be added to the list. ● A method named get_total that returns the total price of all the Retail Item objects stored in the CashRegister object's internal list. A method named show_items that displays data about the Retail Item objects stored in the CashRegister object's internal list. • A method named clear that should clear the CashRegister object's internal list. Demonstrate the Cash Register class in a program that allows the user to select several items for purchase. When the user is ready to check out, the program should display a list of all the items he or she has selected for purchase, as well as the total price.
