<p>Comment (by Roland Haas):</p>
<p>ugh, I did not know that. Checking… Simfactory has “workarounds”: </p>

<p>What’s wrong with <code>os.getlogin()</code> which is the first answer that Google finds for “Python get user name”: <a data-is-external-link="true" href="https://www.geeksforgeeks.org/how-to-get-the-current-username-in-python/" rel="nofollow">https://www.geeksforgeeks.org/how-to-get-the-current-username-in-python/</a> and apparently part of Python since forever?<br>
I’ll make a pull request for simfactory as well.</p>
