Bootstrap environment variables from `.env` file in Python 3

README.md

Storing application variables in a 'hidden' file called .env?

Need to load these variables for dev/testing but didn't start jupyter notebook with them already exported?

Just drop the following into a Python 3 cell.

env.py

## bootstrap environment variables from file
from configparser import RawConfigParser
from itertools import chain
from os import environ

config = RawConfigParser()
with open('.env','r') as f:
    config.read_file(chain(("[DEFAULT]",), f))
    for k,v in config.items('DEFAULT'):
        environ[k.upper().replace('EXPORT ','')] = v
