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.
A static method most_expensive_book that takes…
