De un hilo en python-dev, donde se habla de la transición que hizo
Arch, les traigo este comentario de Barry Barsaw:
In Ubuntu 11.04, we'll have Python 3.1 and 3.2, 2.6 and 2.7, with the default
(i.e. /usr/bin/python) either at 2.6 (probable) or 2.7 (possible). `python3`
currently points to 3.1.2, but we've talked about getting that to 3.2 for this
Ubuntu's next Long Term Support release is scheduled for April 2012. It's an
ambitious but worthy goal to see if we can transition to Python 3 as the
default Python by then.
