python-dotenv
A Python library that loads environment variables from .env files, enabling 12-factor application configuration management.
What is python-dotenv?
python-dotenv is a Python library that loads environment variables from `.env` files into the application's environment. It solves the problem of managing configuration separately from code, especially during development, by allowing developers to store settings in a file that mimics production environment variables. This ensures applications follow the 12-factor app methodology, making them more portable and easier to configure across different environments.
Python developers building 12-factor applications, web developers using frameworks like Django or Flask, and anyone needing to manage environment-specific configuration without hardcoding values.
Developers choose python-dotenv for its simplicity, seamless integration with existing environment variable usage, and adherence to 12-factor principles. It provides a lightweight, zero-dependency solution with advanced features like variable expansion, stream parsing, and a CLI, making configuration management both flexible and robust.
