Give a brief about the settings.py file.

It’s the Django file’s main settings file, as the name says. Everything inside the Django project is saved in this file as a dictionary or list, including databases, middlewares, backend engines, templating engines, installed applications, static file URLs, main URL configurations, authorized hosts, servers, and security keys. When Django files are started, the settings.py file is first executed, followed by the loading of the appropriate databases and engines to swiftly serve the request.
