Defaults to "python"

[Hjaltesorgenfrei]

The config is currently defaulting to python, with no clear difference between python 2 and 3. This is problematic as the kattis platform differs between the two, so it should be either python2 or python3

Since python 2 has been deprecated we should default to python 3 IMO. This would be a non-breaking change since it would only take place on config generation (

Line 60 in 4db3761

"language": "python",

I think that is reasonable. But as long as Kattis allows python2, it should be an option, it still runs faster than python3
