title: How to remove auto escaping from environment variable?
body: <p>In settings.py, I get var from environment like this:</p>
  
  <pre><code>ROBOTS_STR = os.environ.get('DJANGO_ROBOTS_STR')
  </code></pre>
  
  <p>My env var is set in a file and looks like:</p>
  
  <pre><code>DJANGO_ROBOTS_STR=User-agent: *\nDisallow: /admin\nDisallow: /api
  </code></pre>
  
  <p>The problem is that in the view, when I get settings.ROBOTS_STR, the value of the string has been auto escaped. It is: <code>User-agent: *\\nDisallow: /admin\\nDisallow: /api</code></p>
  
  <p>How can I change this behaviour? Note that I'm using Python 3.3</p>
