Reading in environment variables from an environment file
<p>I'd like to run in a local environment a Python script which is normally run in a Docker container. The <code>docker-compose.yml</code> specifies an <a href="https://docs.docker.com/compose/env-file/" rel="noreferrer">env_file</a> which looks (partially) like the following:</p>

<pre><code>DB_ADDR=rethinkdb
DB_PORT=28015
DB_NAME=ipercron
</code></pre>

<p>In order to run this locally, I would like these lines to be converted to</p>

<pre><code>os.environ['DB_ADDR'] = 'rethinkdb'
os.environ['DB_PORT'] = '28015'
os.environ['DB_NAME'] = 'ipercron'
</code></pre>

<p>I could write my parser, but I was wondering if there are any existing modules/tools to read in environment variables from configuration files?</p>
