If I was writing something new today I would use python3, put python3 in
the shebang and just say that it needs python3 as a dependency,
and let the users install it from the package manager if they need it.
The only machines I can think of where python3 may not be available
even as a package are old redhat ones where the version of python2
is so ancient that it doesn't have the compatibility features required
to run py2/py3 code anyway.
