Storing and Changing a Variable in JSON with Python

JSON, or JavaScript Object Notation, is a lightweight format for data interchange that’s easy to read and write for humans and machines alike. If you're working with JSON in Python, you might encounter a scenario where you need to store a number and update it dynamically. This guide will walk you through the process of taking a number from a JSON string, modifying it, and converting it back to JSON format.

The Problem: Updating a Number in JSON

Imagine you have a JSON payload that contains a simple number, such as { "number": 0 }. You want to be able to retrieve this value, increment it by 1, and then store the updated value back in JSON format. This might be useful if you are tracking a score in a game, counting user commands in a bot, or simply needing to track a value over time.

The Solution: Step-by-Step Guide

Here’s how you can achieve this using Python:

Step 1: Import the JSON Library

First, you'll need Python’s built-in json library to help parse and convert between JSON and Python dictionaries.
