In your Python code, you would load the shared file first, then your specific local overrides. : Ensure your file follows the standard format: KEY=VALUE

: Storing secrets in a .env file prevents them from being accidentally committed to version control systems like Git. Developers typically use a python-dotenv package to load these variables into the script's execution context.

# Ignore all .env files .env .env.* # Except for the example/template file !.env.example Use code with caution. Use a Template
