# print all books, add a book and get the number of books using different methods. 
# Show that your program doesn't persist the books after the program is stopped!

# The Library class can be further extended to include additional functionality for managing books in a library.
# For example, methods can be added to remove books, search for books, and update book information.
# The Library class can be used as a foundation for building a library management system in Python.
# The program demonstrates the use of object-oriented programming concepts to create a Library class for managing books in a library.
