Python default versions

[Carmel NY]

Unless I am mistaken, the default version of "python" on FreeBSD is "2.7" The
default version for the "meta-port" for version 3 of the Python interpreter
is "3.4"

I was just wondering if there is any serious consideration to at least
changing the FreeBSD default version to "3.x". Python 3.0 was released in
2008. The final 2.x version 2.7 release came out in mid-2010, Also, could the
default version for the "python3" meta-port be bumped to the latest version,
"3.5".

Finally, is it possible to have two versions of python installed on the same
machine, or would it lead to chaos?
