If you mean that typing "python" runs 2.7, then that's PEP 394 at
work. For compatibility reasons, 'python' doesn't ever run Python 3.
(At least, not any time soon.) The question is more: What comes
installed on a fresh system? Anything can be dragged in as a
dependency of some other package, but a normal Ubuntu desktop
installation won't depend on Python 2 for anything. Or at least,
that's the plan; I don't know whether it's been accomplished yet or
not.
