1) Inherit from Book You create a new class MyBook that uses Book as its base.

2) Constructor with 3 inputs:

title, author, and price

Use super() to send title and author to the parent (Book).

Then use self.price = price to save the price in this class.

3) Use self to store values

self.title, self.author, and self.price This means you’re saving the data inside the object so it can be used later.

4) Implement the display() method print()

Python 3

from abc import ABCMeta, abstractmethod class Book(object, metaclass=ABCMeta): def init(self,title,author): self.title=title self.author=author
@abstractmethod def display(): pass

Write MyBook class

class MyBook: def init(self, title, author, price): self.title = title self.author = author self.price = price def display(self):

    print(f"Title: {self.title}")
    print(f"Author: {self.author}")
    print(f"Price: {self.price}")

title=input() author=input() price=int(input()) new_novel=MyBook(title,author,price) new_novel.display()

----------------MY full code ----- import java.io.; import java.util.;

abstract class Book { String title; String author;

Book(String title, String author) {
    this.title = title;
    this.author = author;
}

abstract void display();

}

class MyBook extends Book { int price;

MyBook(String title, String author, int price) {
    super(title, author);
    this.price = price;
}

void display() {
    System.out.println("Title: " + title);
    System.out.println("Author: " + author);
    System.out.println("Price: " + price);
}

}

public class Solution {

public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);

    String title = scanner.nextLine();
    String author = scanner.nextLine();
    int price = scanner.nextInt();
    scanner.close();

    Book new_novel = new MyBook(title, author, price);
    new_novel.display();
}
