python-dotenv for environment configuration

Reads key-value pairs from a .env file and sets them as environment variables for Python applications.

Python-dotenv automates configuration by loading variables from a local .env file into os.environ. This tool eliminates hardcoded credentials (like API keys or database URIs) and ensures parity between development and production environments. It supports advanced features like variable expansion and command-line integration via the 'dotenv' executable. By calling load_dotenv() at the entry point of a script, developers can access sensitive data securely using standard Python libraries.
