Adding and removing set elements in Python - Mini Project: Build & Apply

Adding and removing set elements

📖 Scenario: You are managing a small library's book collection. You want to keep track of the unique book titles currently available using a set.

🎯 Goal: Build a program that creates a set of book titles, adds a new book to the set, removes a book that is no longer available, and then shows the updated collection.

📋 What You'll Learn

Create a set called books with the exact titles: 'Python Basics', 'Data Science', 'Machine Learning'

Create a variable called new_book with the value 'Deep Learning'

Add the new_book to the books set

Remove the book titled 'Data Science' from the books set

Print the final books set

💡 Why This Matters

🌍 Real World

Libraries and inventory systems often use sets to keep track of unique items like book titles or product IDs.

💼 Career

Understanding how to add and remove elements from sets is useful in data cleaning, managing unique records, and optimizing searches in software development.

1

Create the initial set of books

Create a set called books with these exact titles: 'Python Basics', 'Data Science', and 'Machine Learning'.

Python

# Create the set called books with the given titles
# Your code here

Need a hint?

Use curly braces {} to create a set with the given book titles separated by commas.

2

Add a new book title

Create a variable called new_book and set it to 'Deep Learning'.

Python

books = {'Python Basics', 'Data Science', 'Machine Learning'}
# Create the variable new_book with the value 'Deep Learning'
# Your code here

Need a hint?

Use the assignment operator = to set new_book to the string 'Deep Learning'.

3

Add and remove books from the set

Add the book in new_book to the books set using the add() method. Then remove the book titled 'Data Science' from books using the remove() method.

Python

books = {'Python Basics', 'Data Science', 'Machine Learning'}
new_book = 'Deep Learning'
# Add new_book to books
# Remove 'Data Science' from books
# Your code here

Need a hint?

Use books.add(new_book) to add and books.remove('Data Science') to remove the specified book.

4

Display the updated set of books

Print the books set to show the updated collection after adding and removing books.

Python

books = {'Python Basics', 'Data Science', 'Machine Learning'}
new_book = 'Deep Learning'
books.add(new_book)
books.remove('Data Science')
# Print the books set
# Your code here

Need a hint?

Use print(books) to display the current set of books.
