Looping Through a JSON File with Multiple Sub-Keys in Python: A Simple Guide

Working with JSON files in Python can be a daunting task, especially when you have a structured JSON object containing arrays and nested keys. If you're trying to loop through a JSON file with multiple sub-keys, you're not alone! In this guide, we will break down the solution to extract data effectively from a JSON object representing a group of superheroes.

Understanding the JSON Structure

Let's take a look at an example JSON file that contains a list of members from the "Avengers" group:

In this structure:

group: Displays the name of the group.

members: An array of objects, each representing a member with their properties.

Each member has:

A name

An id

A type

A list of relatives

The Problem

You may find yourself in a situation where you want to extract not just the member's details, but also list each relative individually, without enclosing them in a list.

Consider the following output table you want to achieve:

Your initial approach may yield relatives in a list format, which isn't what you want.

The Solution

Using a for loop, we can achieve this format effortlessly.

Step-by-Step Code Explanation

Load the JSON data.

Iterate through each member of the group.

Within that iteration, loop through each relative.

Print out the required details in a formatted way.

Conclusion

Looping through a JSON file with multiple sub-keys in Python can be simple when you employ nested loops to traverse through the data structure. This method not only makes your code cleaner but also enhances outputs for better readability.

To summarize:

Use for loops to access nested elements.

Keep your data structured and easy to follow.

Format your output to ensure clarity.

With these insights, you're now equipped to tackle any JSON data set you encounter. Happy coding!
