Creating objects in Python - Try It Yourself

Creating objects

📖 Scenario: You are building a simple program to represent a book in a library system. Each book has a title and an author.

🎯 Goal: Create a class called Book and then create an object of this class with specific details. Finally, display the book's title and author.

📋 What You'll Learn

Create a class named Book with an __init__ method that takes title and author as parameters.

Create an object called my_book of the Book class with the title 'The Great Gatsby' and author 'F. Scott Fitzgerald'.

Print the title and author of my_book in the format: Title: The Great Gatsby, Author: F. Scott Fitzgerald.

💡 Why This Matters

🌍 Real World

Creating objects is how we represent real things like books, cars, or people in a program. This helps organize data and behavior together.

💼 Career

Understanding how to create and use objects is essential for many programming jobs, especially in software development and data modeling.

1

Create the Book class

Create a class called Book with an __init__ method that takes self, title, and author as parameters. Inside the method, assign title to self.title and author to self.author.

Python

# Create the Book class with __init__ method
# Your code here

Need a hint?

Remember, the __init__ method is used to initialize the object's attributes.

2

Create an object of the Book class

Create an object called my_book of the Book class with the title 'The Great Gatsby' and author 'F. Scott Fitzgerald'.

Python

class Book:
    def __init__(self, title, author):
        self.title = title
        self.author = author

# Create the my_book object with title 'The Great Gatsby' and author 'F. Scott Fitzgerald'
# Your code here

Need a hint?

Use the class name Book followed by parentheses with the title and author as arguments.

3

Access object attributes

Use my_book.title and my_book.author to access the title and author of the book. Create a string variable called book_info that stores the text: Title: The Great Gatsby, Author: F. Scott Fitzgerald using an f-string.

Python

class Book:
    def __init__(self, title, author):
        self.title = title
        self.author = author

my_book = Book('The Great Gatsby', 'F. Scott Fitzgerald')

# Create book_info string using my_book.title and my_book.author
# Your code here

Need a hint?

Use an f-string to combine the title and author into one string.

4

Print the book information

Print the variable book_info to display the book's title and author.

Python

class Book:
    def __init__(self, title, author):
        self.title = title
        self.author = author

my_book = Book('The Great Gatsby', 'F. Scott Fitzgerald')

book_info = f"Title: {my_book.title}, Author: {my_book.author}"

# Print the book_info variable
# Your code here

Need a hint?

Use the print() function to show the book information.
