Updated environment variable but os.getenv() keeps returning None
<p>I can't seem to get my code to respond to custom environment variables  so I wrote a piece of code to test it. <code>os.getenv</code> is not pulling the environment variables that I've set in BASH into my Python code.</p>
<pre class="lang-bash prettyprint-override"><code>$ FRUSTRATION=&quot;PYTHON!!&quot;
$ echo $FRUSTRATION
PYTHON!!
$ ipython
In [1]: import os

In [2]: very_frustrated = os.getenv(&quot;FRUSTRATION&quot;)

In [3]: print(very_frustrated)
None
</code></pre>
