RELEASE_NUMBER=12
ENV=dev

Then specify your config:

from envconfig import param
from envconfig import EnvConfig


class AppConfig(EnvConfig):
    """App env config."""

    HOST = param.Str(required=True)
    PORT = param.Int(required=True)
    PASSWORD = param.Str(override="SECRET_REDIS_PW", required=True)

    SERVICE = param.Str(prefix="MY_APP_")
    VERSION = param.Int(override="RELEASE_NUMBER")
    ENV = param.Str(default="prod")


config = AppConfig()

# Access by class attribute or subscript
config.USER
config["USER"]

Setup flask config:

config = AppConfig()
app.config.from_object(config)

Point to a .env file

config = AppConfig("./.env")

Some functionality provided by dotenv
