COSC 1336 –
Fundamentals I Python Programming
Write a class named RetaiI_Item that holds data about an item in a retail store.
The class should store the following data in attributes:
• Item Number
• Item Description
• Units in Inventory
• Price
Create another class named Cash_Register that can be used with the Retail_Item class. The Cash_Register class should be able to internally keep a list of Retail_Item objects. The class should include 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
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_Items objects stored in the Cash_Register’s internal list.
• A method named show_items that displays data about the Retail_Item
objects stored in the Cash_Register object’s internal list.
• A method named clear_items that should clear the Cash_Register
object’s internal list.
Write a main function that uses the Cash_Register class to allow 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, taxes, and the final price.
Run your program, with your own data, and copy and paste the output to a file

A Volume will have properties such as volumeName, numberOfBooks, and an array of book objects (Book [ ]). You are required to develop the Book and Volume classes, then write an application (DemoVolume) to test your classes. The directions below will give assistance. Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, Create a second class called Volume with the following properties using appropriate data types: volumeName, numberOfBooks and Book [ ]. The Book [ ] contains an array of book objects. Directions Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, The only methods necessary in the Book class, for this exercise, are the constructor and a toString().
