How does it determine what is appropriate?

If the script is already compiled to a .pyc, you can probably find out which version of Python compiled it (I never tried that because, frankly, I'm very happy with having python and python3 on /usr/bin).

That's determining which python already ran it, not which python it needs.
I don't believe it's very decidable.

They look at shebang line. #!python2 to 2, #!python3 to 3, #!python defaults to 2 (configurable).

So the same as Linux then?

py.exe on Windows solves a completely different issue: where is Python installed and how do I invoke it? All pythons (2, 3.4, 3.5, etc) are called python.exe, so putting it in PATH is not an option.
