A library wants to manage its collection of books and authors more efficiently. They would like to create a Python program to help with this task. The following requirements need to be implemented:
Create an Author class with the attributes: name, dob (date of birth), and nationality. The class should have a __str__ method to represent the author in a user-friendly format.
Create a Book class with the following attributes: title, author (an instance of the Author class), publication_date, and price. Also, include a class variable all_books that keeps a list of all book instances created.The Book class should have:
A __str__ method to represent the book in a user-friendly format.
A __eq__ method to compare two books. Two books are considered the same if they have the same title and author.
A __lt__ method to compare two books based on their publication dates.
A class method get_all_books that returns a list of all books in the library.

This tips will help you What You Must Implement:You must define a class named MediaRental that implements the MediaRentalInt interface functionality(index A). You must define classes that support the functionality specified by the interface. The followingspecifications are associated with the project:1. Define a class named MediaRental. Feel free to add any instance variables you understand are needed or anyprivate methods. Do not add any public methods (beyond the ones specified in the MediaRentalInt interface).2. The media rental system keeps track of customers and media (movies ,music albums and games). A customerhas a name, address as string , a plan and two lists. One list represent the media the customer is interested inreceiving and the second one represents the media…arrow_forwardInstructor note: This lab is part of the assignment for this chapter. This lab uses two Java files, LabProgram.java and SimpleCar.java. The SimpleCar class has been developed and provided to you already. You don't need to change anything in that class. Your job is to use the SimpleCar class to complete the specified tasks in the main() method of LabProgram.java Given two integers that represent the miles to drive forward and the miles to drive in reverse as user inputs, create a SimpleCar object that performs the following operations: Drives input number of miles forward Drives input number of miles in reverse Honks the horn Reports car status The SimpleCar class is found in the file SimpleCar.java. Ex: If the input is: 100 4 the output is: beep beep Car has driven: 96 milesarrow_forwardIn c++ Create a new project named lab11_1. You will be implementing three classes: A Clothing class, a Shirt class, derived from Clothing and third class of your choice that will be derived from Clothing. I have included the UML diagrams for Clothing and Shirt. You will need to make sure that the class you derive from Clothing is appropriate, meaning it makes sense that it would inherit from Clothing. In your driver file, I’d like to see a Shirt object created, as well as an object of the class type that you create. Set the class variable members to specific values, and then print. You can choose to override the output operator to make this easier, or you can implement a method named print(). Create a new project named lab11_2. Come up with your own base class, and derived class. No big specifications here on what you need to do (in terms of overloading operators, friend functions, static variables, composition, etc), but you have to make use of the base class members in the derived…arrow_forward

Write a class named Employee that has private data members for an employee's name, ID_number, salary, and email_address. It should have an init method that takes four values and uses them to initialize the data members. It should have get methods named get_name, get_ID_number, get_salary, and get_email_address. Write a separate function (not part of the Employee class) named make_employee_dict that takes as parameters a list of names, a list of ID numbers, a list of salaries and a list of email addresses (which are all the same length). The function should take the first value of each list and use them to create an Employee object. It should do the same with the second value of each list, etc. to the end of the lists. As it creates these objects, it should add them to a dictionary, where the key is the ID number and the value for that key is the whole Employee object. The function should return the resulting dictionary. For example, it…arrow_forward

Implementing the public interface as described is madatory. There's freedom on how to implement these classes.The private properties and private methods are under your control.. There are multiple ways of implementing all these classes. Feel free to add private properties and methods. For each object, it's mandatory to create a header file (.h), implementation file (.cpp) and a driver. Blank files are included. The header should have the class definition in it. The implementation file should contain the implementations of the methods laid out in the header fine. And finally the Driver should test/demonstrate all the features of the class. It's best to develop the driver as the class is being written. Check each section to see if there are added additional requirements for the driver. Two test suites are included so that work can be checked.
