Yes: Python 3.6 I've been doing my testing with Python 3.6 on Windows and then uploading here for deployment. I saw the post http://www.helionet.org/index/topic/23326-answered-python-issue/ that gave the Python 3 shebang (#!/usr/local/bin/python3.4) and could not figure out why it failed until reading this post. I explored other free hosting sites but, I must say, your service and design and control panel are among the very best I could find. So, if you can provide any version of Python 3 under Johnny, I'd be very grateful because it will save me a ton of work coding version dependent logic. Thanks!
