Resource identifiers in URLs in Rest API - Mini Project: Build & Apply

Resource Identifiers in URLs

📖 Scenario: You are building a simple REST API for a bookstore. Each book has a unique ID. You want to create URLs that identify each book resource clearly and simply.

🎯 Goal: Build a list of book URLs using resource identifiers (book IDs) in the URL path.

📋 What You'll Learn

Create a list of book IDs

Create a base URL string

Use a loop to build full URLs for each book by adding the book ID to the base URL

Print the list of full book URLs

💡 Why This Matters

🌍 Real World

APIs use resource identifiers in URLs to let users and programs find specific items like books, users, or orders easily.

💼 Career

Understanding how to build and use resource URLs is essential for backend developers, API designers, and anyone working with web services.

1

Create the list of book IDs

Create a list called book_ids with these exact values: 101, 102, 103, 104, 105

Rest API

# Create the list of book IDs
# Your code here

Need a hint?

Use square brackets [] to create a list and separate numbers with commas.

2

Create the base URL string

Create a string variable called base_url and set it to "https://api.bookstore.com/books/"

Rest API

book_ids = [101, 102, 103, 104, 105]
# Create the base URL string
# Your code here

Need a hint?

Use double quotes "" to create the string.

3

Build full URLs for each book

Create an empty list called book_urls. Then use a for loop with variable book_id to iterate over book_ids. Inside the loop, append the full URL string formed by joining base_url and the string version of book_id to book_urls.

Rest API

book_ids = [101, 102, 103, 104, 105]
base_url = "https://api.bookstore.com/books/"
# Create an empty list called book_urls
# Use a for loop with book_id to iterate over book_ids
# Append full URLs to book_urls
# Your code here

Need a hint?

Remember to convert the number book_id to a string before joining it with base_url.

4

Print the list of full book URLs

Write a print statement to display the book_urls list.

Rest API

book_ids = [101, 102, 103, 104, 105]
base_url = "https://api.bookstore.com/books/"
book_urls = []
for book_id in book_ids:
    book_urls.append(base_url + str(book_id))
# Print the list of book URLs
# Your code here

Need a hint?

Use print(book_urls) to show the list.
