Comment (by Chris Johns):

 Replying to [comment:1 Sebastian Huber]:
 > Do we have a host platform without python3 support? If not, then I would
 simply use python3 and stop using python/python2.
 In time we will need to switch to `python3` however I am not in a position
 to go over all the code and do this. I think it also makes things
 difficult or at least more complicated for users with established
 environment to get such a hard error. We should consider a softer landing
 if this is possible.
 I am considering moving to a shell script that checks for `python2` then
 `python3` and if not found outputs a user friendly error message. The
 existing code is moved into the python directories run from the python
 command line. Once we are happy with `python3` we can switch the order we
 check.
 A script would let us add an environment variable we could use to force a
 version to test with without needing symlinks etc.
