How to share data between python processes without writing to disk

In some applications, it's necessary to share data between different Python processes without resorting to writing data to disk, which can be time-consuming and resource-intensive. Interprocess communication (IPC) provides a solution to this problem. In this tutorial, we'll explore how to achieve data sharing between Python processes using the multiprocessing module without the need for writing to disk.
Make sure you have Python installed on your machine. This tutorial assumes you are using Python 3.
We'll be using the multiprocessing module for creating and managing processes. If you don't have it installed, you can install it using:
The multiprocessing module provides the Value and Array classes for creating shared memory between processes. Let's create a simple example:
