Python 3 Project

Project Details: Project 6 will add additional features to the code from Project 5 code. We will now split the BookData class into 2 classes. BookData will now only use the bookTitle, isbn, author, and publishers. Create a new class called InventoryBook. This class will derive from the BookData class and use the dateAdded, qtyOnHand, wholesale, and retail attributes. Move the functions into their correct class and fix the list of object creation to create the correct objects. Create another class called SoldBook. This class will derive from the InventoryBook class. It will have the following attributes: taxRate - A private static member, used to hold the sales tax rate qtySold - The quantity of a particular book that is being purchased subtotal - The subtotal of the sale of a particular title. The subtotal is calculated as retail times qtySold tax - The sales tax on the purchase of a particular book, calculated as subtotal times taxRate(retail is inherited from InventoryBook.) total - A private static member used to hold the total of an entire sale Create all of the needed functions too. Modify the cashier function to use these new classes. Don’t worry about doing anything for the other functions based on these changes. We will do that in Project 7. This means, when testing your code, only use the Cashier function and make sure that works. So if it touches the LookUpBook function, then you have to fix that one. You only have to do one interaction with the SoldBook, we will add a loop to the cashiers function in Project 7.
