Explanation

Abstract base classes have some abstract methods and these methods have to implemented in child classes.
If you want to enforce the implementation of a method in subclasses, you need to write @abstractmethod before the method definition in the main class.

My Python 3 Solution:

#Write MyBook class
class MyBook(Book):
    def __init__(self, title, author, price):
        super().__init__(title, author)
        self.price = price
    
    def display(bored_from_self):
        print("Title:", bored_from_self.title)
        print("Author:", bored_from_self.author)
        print("Price:", bored_from_self.price)

My C# sol:

class MyBook:Book{
    private int _price;
    private string _title;
    private string _author;
    public MyBook(string title,string author,int price):base(title,author){
        _price=price;
        _title=title;
        _author=author;
    }
    public override void display(){
        Console.WriteLine("Title: "+_title);
        Console.WriteLine("Author: "+_author);
        Console.WriteLine("Price: "+_price);
        
    }
}
