JSON as standard format in Rest API - Mini Project: Build & Apply

Using JSON as Standard Format in REST API

📖 Scenario: You are building a simple REST API that sends and receives data in JSON format. JSON is a common way to share data between computers because it is easy to read and write.

🎯 Goal: Learn how to create a Python dictionary with data, convert it to JSON format, and print the JSON string. This simulates sending data in a REST API response.

📋 What You'll Learn

Create a Python dictionary with specific data

Create a variable to hold the JSON string

Convert the dictionary to a JSON string using the json module

Print the JSON string

💡 Why This Matters

🌍 Real World

APIs use JSON to send data between servers and apps because JSON is easy to read and write for both humans and machines.

💼 Career

Understanding JSON is essential for backend and frontend developers working with REST APIs, which are common in web and mobile app development.

1

Create the data dictionary

Create a dictionary called user_data with these exact entries: 'name': 'Alice', 'age': 30, 'city': 'New York'

Rest API

# Create the dictionary user_data with name, age, and city
# Your code here

Need a hint?

Use curly braces {} to create a dictionary. Separate keys and values with a colon.

2

Import json module and prepare JSON string variable

Import the json module and create a variable called json_string to hold the JSON data (leave it empty for now).

Rest API

user_data = {'name': 'Alice', 'age': 30, 'city': 'New York'}
# Import json module and create json_string variable
# Your code here

Need a hint?

Use import json to bring in the JSON tools. Create json_string and set it to an empty string.

3

Convert dictionary to JSON string

Use json.dumps() to convert user_data to a JSON string and store it in json_string.

Rest API

import json
user_data = {'name': 'Alice', 'age': 30, 'city': 'New York'}
json_string = ''
# Convert user_data to JSON string and store in json_string
# Your code here

Need a hint?

Use json.dumps() to turn a dictionary into a JSON string.

4

Print the JSON string

Print the variable json_string to display the JSON formatted data.

Rest API

import json
user_data = {'name': 'Alice', 'age': 30, 'city': 'New York'}
json_string = json.dumps(user_data)
# Print the JSON string
# Your code here

Need a hint?

Use print(json_string) to show the JSON data.
