💼 Career

Understanding search and filtering is essential for data handling, user interfaces, and improving user experience in many jobs.

1

Create the list of books

Create a list called books with these exact entries as dictionaries: {'title': 'The Hobbit', 'genre': 'Fantasy'}, {'title': '1984', 'genre': 'Dystopian'}, {'title': 'To Kill a Mockingbird', 'genre': 'Classic'}, {'title': 'The Great Gatsby', 'genre': 'Classic'}, and {'title': 'Brave New World', 'genre': 'Dystopian'}.

No-Code

# Create the list of books with title and genre
# Your code here

Need a hint?

Use a list of dictionaries where each dictionary has keys 'title' and 'genre'.

2

Add the search keyword variable

Create a variable called search_keyword and set it to the string 'the' (all lowercase).

No-Code

books = [
    {'title': 'The Hobbit', 'genre': 'Fantasy'},
    {'title': '1984', 'genre': 'Dystopian'},
    {'title': 'To Kill a Mockingbird', 'genre': 'Classic'},
    {'title': 'The Great Gatsby', 'genre': 'Classic'},
    {'title': 'Brave New World', 'genre': 'Dystopian'}
]
# Create the search keyword variable
# Your code here

Need a hint?

Set the variable exactly as search_keyword = 'the'.

3

Filter books by title containing the search keyword

Create a list called filtered_books that contains only the books from books where the search_keyword appears in the book's title (case insensitive). Use a list comprehension with book as the iterator variable.

No-Code

books = [
    {'title': 'The Hobbit', 'genre': 'Fantasy'},
    {'title': '1984', 'genre': 'Dystopian'},
    {'title': 'To Kill a Mockingbird', 'genre': 'Classic'},
    {'title': 'The Great Gatsby', 'genre': 'Classic'},
    {'title': 'Brave New World', 'genre': 'Dystopian'}
]

search_keyword = 'the'
# Create filtered_books list with books whose title contains search_keyword (case insensitive)
# Your code here

Need a hint?

Use book['title'].lower() to check the title in lowercase.

4

Add genre filtering to the search

Create a variable called selected_genre and set it to 'Classic'. Then update filtered_books to include only books where the title contains search_keyword (case insensitive) and the genre matches selected_genre exactly. Use the same list comprehension style with book as the iterator variable.

No-Code

books = [
    {'title': 'The Hobbit', 'genre': 'Fantasy'},
    {'title': '1984', 'genre': 'Dystopian'},
    {'title': 'To Kill a Mockingbird', 'genre': 'Classic'},
    {'title': 'The Great Gatsby', 'genre': 'Classic'},
    {'title': 'Brave New World', 'genre': 'Dystopian'}
]

search_keyword = 'the'

filtered_books = [book for book in books if search_keyword in book['title'].lower()]

# Create selected_genre variable and update filtered_books to filter by genre too
# Your code here

Need a hint?

Check both conditions with and inside the list comprehension.
