title: How to use environment variables in Python in Glitch
body: <p>I am working on a Python API project on the Glitch platform and I didn't find anything on how to reference the .env file and use the variables in a python script. <code>os.environ</code> will not work because I haven't imported anything to the app. How should I reference it properly and how should I import the module correctly?</p>
  
  <pre><code>import os
  var = os.environ['SECRET_NAME']  # Will raise a KeyError if not existed
  var2 = os.environ.get('SECRET_NAME')  # Will give a value of 'None" if not existed 
  </code></pre>
