Currently recommended Python version?

[Craig Treleaven]

I was about to update one of my ports, libcec, which currently depends on python34.  I see that python37 was added to MacPorts in the middle of 2018.  I don’t even know how libcec actually uses python.  I can’t see anything documented for the package that specifies or recommends a particular version.

Which version of python 3 should I use?
