python-decouple

python-decouple provides a clean, strict separation of configuration settings from code, inspired by The Twelve-Factor App methodology. It allows you to store parameters in environment variables, `.env` files, or `settings.ini` files, making it easy to manage different environments (development, staging, production). The current version is 3.8, and it sees active maintenance with minor releases typically a few times a year addressing bug fixes and minor improvements.
