Environment variables are a crucial aspect of modern web development, allowing developers to configure and manage application settings without hardcoding values directly into the code. In this tutorial, we will explore how to use environment variables in a Django project to enhance flexibility and security.
Before we begin, ensure that you have the following installed:
If you haven't already, create a new Django project using the following commands in your terminal:
