String formatting using f-strings in Python - Mini Project: Build & Apply

String formatting using f-strings

📖 Scenario: You are creating a simple program to display information about a book in a friendly way. You want to show the book's title, author, and year of publication in a sentence.

🎯 Goal: Build a program that uses f-strings to format and display a sentence with the book's details.

📋 What You'll Learn

Create variables for the book's title, author, and year.

Create a variable for a short message prefix.

Use an f-string to combine the variables into a full sentence.

Print the formatted sentence.

💡 Why This Matters

🌍 Real World

Formatting strings nicely is useful for showing information clearly in apps, reports, or messages.

💼 Career

Many programming jobs require creating readable output for users, and f-strings make this easy and clean.

1

Create variables for book details

Create three variables: title with the value "The Great Gatsby", author with the value "F. Scott Fitzgerald", and year with the value 1925.

Python

# Your code here

Need a hint?

Use simple assignment statements to create the variables with the exact names and values.

2

Create a message prefix variable

Create a variable called message and set it to the string "Book Info:".

Python

title = "The Great Gatsby"
author = "F. Scott Fitzgerald"
year = 1925
# Your code here

Need a hint?

Just assign the string to the variable message.

3

Create a formatted string using f-string

Create a variable called formatted that uses an f-string to combine message, title, author, and year into this exact sentence: Book Info: "The Great Gatsby" by F. Scott Fitzgerald, published in 1925.

Python

title = "The Great Gatsby"
author = "F. Scott Fitzgerald"
year = 1925
message = "Book Info:"
# Your code here

Need a hint?

Use an f-string with curly braces to insert the variables inside the string.

4

Print the formatted string

Write a print statement to display the formatted string.

Python

title = "The Great Gatsby"
author = "F. Scott Fitzgerald"
year = 1925
message = "Book Info:"
formatted = f'{message} "{title}" by {author}, published in {year}.'
# Your code here

Need a hint?

Use print(formatted) to show the final sentence.
