204 No Content in Rest API - Mini Project: Build & Apply

Understanding 204 No Content in REST API

📖 Scenario: You are building a simple REST API for a to-do list application. When a user deletes a task, the server should respond with a 204 No Content status code to indicate the deletion was successful but there is no content to return.

🎯 Goal: Create a REST API endpoint that deletes a task by its ID and returns a 204 No Content response.

📋 What You'll Learn

Create a data structure to hold tasks with IDs and descriptions

Add a variable to specify the ID of the task to delete

Write the logic to delete the task from the data structure

Return a 204 No Content response after deletion

💡 Why This Matters

🌍 Real World

APIs often need to delete resources and respond with 204 No Content to confirm success without sending extra data.

💼 Career

Understanding HTTP status codes like 204 is essential for backend developers and API designers to communicate clearly with clients.

1

DATA SETUP: Create the initial tasks data structure

Create a dictionary called tasks with these exact entries: 1: 'Buy groceries', 2: 'Read a book', 3: 'Write code'

Rest API

# Create the tasks dictionary with IDs and descriptions
# Your code here

Need a hint?

Use a Python dictionary with integer keys and string values.

2

CONFIGURATION: Specify the task ID to delete

Create a variable called task_id_to_delete and set it to 2

Rest API

tasks = {1: 'Buy groceries', 2: 'Read a book', 3: 'Write code'}
# Set the task ID to delete
# Your code here

Need a hint?

Just assign the number 2 to the variable task_id_to_delete.

3

CORE LOGIC: Delete the task from the dictionary

Use del tasks[task_id_to_delete] to remove the task with ID 2 from the tasks dictionary

Rest API

tasks = {1: 'Buy groceries', 2: 'Read a book', 3: 'Write code'}
task_id_to_delete = 2
# Delete the task with ID 2
# Your code here

Need a hint?

Use the del keyword to remove the key from the dictionary.

4

OUTPUT: Return a 204 No Content response

Print the exact string '204 No Content' to simulate the API response after deletion

Rest API

tasks = {1: 'Buy groceries', 2: 'Read a book', 3: 'Write code'}
task_id_to_delete = 2
del tasks[task_id_to_delete]
# Print the 204 No Content response
# Your code here

Need a hint?

Use print('204 No Content') exactly.
