python-readenv 0.3.1

read an env file and export to os.environ

python-readenv

readenv makes it easy to automatically load environment variables from .env file(s) and put into os.environ.

Install

$ pip install python-readenv

Getting started

You can automatically load at startup time with the helper import import readenv.loads, which try to locate and load the first env file found from your current working directory up to root. By default it will search for .env and .env.local files.

Automatic load

You can automatically load at startup time with the helper import

import readenv.loads

...

which try to locate and load the first env file found from your current working directory up to root.

Manual load

Alternatively, you can customize which files readenv should search and load

import readenv

readenv.load("myenv", "myenv.local")

Custom environment

You can create your own environment

import readenv

env = readenv.Environ()

or start with the current environ copy

import copy
import os
import readenv

env = Environ(copy.deepcopy(os.environ))
