Python version 3.6 not supported

[paul-calvelage]

I was attempting the "Geometry Basics: Distance between points in 2D"
(https://www.codewars.com/kata/geometry-basics-distance-between-points-in-2d/train/python) kata today and ran into this error when clicking "Run Sample Tests" or "Attempt":

For this particular kata, Python 3.6 appears to be the only version I can select, as the others are greyed out:

I can reproduce the "python version 3.6 not supported" message on other Python kata that have the 3.6.0 option.

@kazk this can be closed with the new front end finally supporting 3.6 properly.

Thanks, this was actually caused by the request payload having number 3.6 as language version (I think). The new runner is little bit nicer and accepts it.
I tried to find the source of this bug (why the language version is sometimes given as a number), but eventually gave up.
