Create a file called Bookshelf, py and define a class named BookShelf to model a bookshelf in a library. The class contains:

a$.$ One private instance int data field book$\_$id that represents the id of the book.

b$.$ One private instance data field named book$\_$details which is a dictionary that will hold all the books in the shelf. It stores key$-$value pairs, where a key is a book id and value is an object of class Book.

c$.$ A constructor that initializes book$\_$id to $0$ and creates an empty dictionary book$\_$details.

d$.$ A method named add$\_$book $()$ that accepts an object of type Book as a parameter, increments book$\_$id by $1$ and inserts book$\_$id and the book object as key and value in book$\_$details.

e$.$ A method named remove book $()$ that accepts an int id as a parameter. It checks if id is present in the keys of book details. If yes, it deletes the entry of the book with the given id$.$ If not, it displays a string "Book with the given id not found".

f$.$ A method named get title author $()$ that accepts id as a parameter. It checks if id is present in the keys of book details. If yes, it returns title and author of the book with the associated id as a tuple. You will need to invoke the get$\_$title$()$ and get$\_$author $()$ methods of Book class on the book object.

g$.$ A method named get book$\_$id$()$ that accepts title as a parameter. It returns the id for the given title. You will need to invoke the get$\_$ title$()$ method of Book class. The method returns $-1$ if the book with given title is not found.

h$.$ A method named check$\_$out$\_$book$()$ that accepts id as a parameter. It checks if id is present in the keys of book details. If not, it displays a string "Book with the given id not found". If yes, it checks if the book with the associated id is already checked out by invoking is$\_$checked$\_$out $()$ method of the Book class. If the method returns true, display a string "Book not in the library.". If it is not checked out, invoke the check$\_$out $()$ method of the Book class on the book.

i$.$ A method named return book$\_$to$\_$shelf$()$ that accepts id as a parameter. It checks if id is present in the keys of book$\_$details. If not, it displays a string "Book with the given id not found". If yes, it invokes the return$\_$book$()$ method of the Book class on the book with the associated id$.$

j$.$ A method named get$\_$inventory$()$ that prints every book in the dietionary book$\_$details in the following format:

Id: $1$ Title: Book I Author: Author I Check Out Status: False

Where $1,$ Book$1,$ Author$1,$ and False are the values of the variables id$,$ title, author, and checked$\_$out, respectively. You will have to invoke the get$\_$title$(),$ get$\_$author $()$ and is$\_$checked$\_$out $()$ methods of the Book class.
