title: os.getenv('TOKEN') returns None with TOKEN defined in .env
body: <p>In the same folder, I have an <code>.env</code> file and a <code>main.py</code> file.</p>
  <p>In <code>.env</code> I have set</p>
  <pre><code>TOKEN = 123456
  </code></pre>
  <p>And in <code>main.py</code> I have</p>
  <pre class="lang-py prettyprint-override"><code>import os
  print(os.getenv('TOKEN'))
  </code></pre>
  <p>When I run the Python script, I get <code>None</code> in the standard output. What am I doing wrong?</p>
  <p>I have looked at all the similar questions but it seems like I'm not missing any steps. I'm using MacOS if that affects anything.</p>
  <p>Thanks in advance!</p>
