What is Python-Decouple?

Python-Decouple is a simple yet powerful tool that helps manage Django configuration settings securely. Instead of hardcoding secrets like SECRET_KEY or database credentials in settings.py, it allows you to store them in environment variables or a .env file, keeping your codebase clean and safe.

Why Use Python-Decouple?

Better security – Keeps sensitive data out of your code.
Easy environment switching – Quickly adapt configurations for development, staging, and production.
Less clutter in settings.py – Keeps settings organized and modular.
Automatic type conversion – Easily manage strings, integers, and lists.
Seamless integration – Works with Django, CI/CD pipelines, and containerized deployments.
