pip install python-dotenv
This package will take care of our environment variables.
Environment variables change based on the environment in which we're running our Django project (production, development...).
DEBUG; this variable should be False in production, and True in our local environment.
This is why we're going to create a separate file called (.env) that will hold our DEBUG variable. The file won't be staged to version control. Then we're going to create the .env file manually in our production environment, it will also hold our debug variable but with a different value.
