Sounds like you&#x27;re a lone wolf at a smaller company. Different ballgame from the &quot;longtime Python devs&quot; that I&#x27;m talking about. I had an employer with a 500KLOC Python2 codebase, a billion dollar business on the line, and new features to deliver. That 2020 date is just a big political stunt. As was 2015 or it wouldn&#x27;t have been a snap of the fingers to extend it. Code won&#x27;t stop working in 2020 and security is largely handled by a webserver.<p>I use Python3 sometimes as well, but doesn&#x27;t mean what I&#x27;m saying isn&#x27;t true.
