Step $1$: Designing the Core Classes

$1.$ Book Class Design: Create a class called Book with attributes $($ title, author, genre, and

availability status$).$ Include a method within the class to check the availability of the book.

$2.$ Library Class Construction: Develop a class named Library that initializes an empty list to store

books. Implement methods to add books to the library, remove books, and search for books

by title, author, or genre.

Step $2$: Handling Different Types of Materials

$1.$ Specialized Material Types:

$$ Utilize inheritance to derive specialized Material types like Books, DVDs$,$ and Journals

from a parent class, called Material.

$$ Each subclass should have unique attributes$/$methods relevant to its type, such as ISBN

for books, duration for DVDs$,$ and publication date for Journals.

$2.$ Library Functionality Expansion:

$$ Enhance the Library class to manage different material types efficiently.

$$ Implement methods to:

$$ Display the available materials for each type.

$$ Calculate the total count of materials per type.
