Environment Variables

pip install python-dotenv

python-dotenv reads key-value pairs from a .env file and sets them as environment variables

.env (git ignore this)

CONFIG_PATH=${HOME}/.config/foo
DOMAIN=example.org
EMAIL=admin@${DOMAIN}

script.py

from dotenv import load_dotenv
import os

load_dotenv()

SECRET_KEY = os.getenv("EMAIL")
DATABASE_PASSWORD = os.getenv("DATABASE_PASSWORD")

flask run auto does this
