What version of python has this been tested with?

I tried running somecomfort -h with Python 3.5.2 and got

Traceback (most recent call last):

prettytable dropped support for Python 3.5 after version 1.x. You appear to somehow have installed pretty table 2.x in your 3.5 installation. Trying downgrading to prettytable 1.0.1. I have no idea if somecomfort supports this version of prettytable, but if you need to use 3.5 this is worth a shot.
