#42747 closed enhancement (duplicate)

"port python --select" should offer "python3" and "python2" options

Description

As documented in Python PEP 394 (http://legacy.python.org/dev/peps/pep-0394/), it is problematic and not currently recommended to use "python" as a synonym for a Python 3 version. Recommended upstream practice is to offer "python3' as a synonym for the current preferred Python 3 version, "python2" for the current preferred Python 2 version, and, during the long transition period from Python 2 to Python 3, recommend "python" be the same as "python2" but eventually moving to "python3". In support of this, "port select --python" should support "python3" and "python2" groups.

Yes, I just got bitten by this one too: there are python programs written in Python 3.x which begin with #! /usr/bin/env python3, which won't run under macports because there's no python3 symlink :-(
