Classes and objects in Python - Mini Project: Build & Apply

Classes and Objects

📖 Scenario: You are creating a simple program to manage information about books in a library. Each book has a title and an author.

🎯 Goal: Build a class called Book to represent a book with a title and author. Then create an object of this class and display its details.

📋 What You'll Learn

Create a class named Book with two attributes: title and author.

Create an object of the Book class with specific title and author.

Print the book's title and author using the object's attributes.

💡 Why This Matters

🌍 Real World

Classes help organize data and behavior for real-world things like books, users, or products in software.

💼 Career

Understanding classes and objects is essential for software development jobs, especially in object-oriented programming.

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, set self.title to title and self.author to author.

Python

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

Need a hint?

Remember, the __init__ method sets up the object's attributes when you create it.

2

Create a Book object

Create an object called my_book from 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 here
# Your code here

Need a hint?

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

3

Access object attributes

Create two variables: book_title and book_author. Set book_title to my_book.title and book_author to my_book.author.

Python

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

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

# Assign book_title and book_author from my_book
# Your code here

Need a hint?

Use dot notation to get the attributes from the object.

4

Print the book details

Write a print statement to display the text: "Title: {book_title}, Author: {book_author}" 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')

book_title = my_book.title
book_author = my_book.author

# Print the book details below
# Your code here

Need a hint?

Use an f-string to insert variables inside the string.
