How to Filter and Print JSON Output in Python

JSON (JavaScript Object Notation) is a popular data format often used for exchanging data between a server and a web application. Often, developers need to filter through this data to retrieve only the fields relevant to their needs. In this guide, we will learn how to effectively filter JSON data in Python to achieve this goal.

The Problem

Imagine you have a large JSON object but are only interested in extracting a couple of fields. For example, you might have JSON output containing various information about a group, including its status and other metrics, as shown below:

You want to print only specific pieces of this data, namely:

mode

state

However, your current implementation might not yield the expected results. Let's explore how you can accomplish this with the appropriate Python code.

Step-by-Step Solution

1. Set Up the JSON Data

First, you need to have your JSON data structured correctly in Python. For the sake of this guide, we'll create a JSON object resembling the original output:
