Converting Multidimensional Lists to JSON in Python

Working with data in Python often involves manipulating arrays and converting them into different formats. One common task is converting a multidimensional list into JSON format, which is widely used for data interchange between APIs. If you're struggling with this task, don't worry! In this post, we’ll guide you step-by-step to achieve this transformation effortlessly.

The Problem

You might have a multidimensional list, such as this:

In your case, you might have attempted various methods and encountered unexpected results. Let’s break down the solution to this problem in a way that is clear and straightforward.

Solution Breakdown

Step 1: Set Up Your List

Start by creating the multidimensional list (array) that you want to convert to JSON. For example:

Step 2: Convert to a Dictionary

To transform the list into a JSON-friendly format, we will convert it into a dictionary first. This can be done using a simple loop:

In this snippet:

We initialize an empty dictionary d.

We loop through each sublist a in arr and assign the first element (month name) as a key and the second element (value) as its corresponding value in the dictionary.

Step 3: Wrap it in a JSON Structure

Next, we need to create a final result that includes the year and the dictionary we just built:

Now, result holds the full JSON structure you wanted.

Step 4: Convert to JSON String

To get the final JSON string representation, you can use Python's json module:
