Installed Python from Package, Terminal didn't update?

Question

Terminal is still showing Python 2.7.2 after an install of 3.3.0

I'm new to python- just want to get a good development environment working on Mac 10.8.

use `python3` instead of `python` – Ashwini Chaudhary Mar 08 '13 at 00:09 — Ashwini Chaudhary, Mar 08 '13 at 00:09

Use python3 instead of python:

$ python3
Python 3.2.3 (default, Oct 19 2012, 19:53:57) 
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.

If you're new then I would suggest you to use [IPython](http://ipython.org/), it provides some additional features compared to normal python shell. – Ashwini Chaudhary Mar 08 '13 at 00:16
i'm doing some looking around, would you also recommending using pip for installing modules or should i try to use macports. i'm a front-end web developer so this is all a new world for me – rob-gordon Mar 08 '13 at 00:18
I am not a mac user, so can't say anything about that. This might help: http://stackoverflow.com/questions/1213690/what-is-the-most-compatible-way-to-install-python-modules-on-a-mac – Ashwini Chaudhary Mar 08 '13 at 00:23

See PEP 394:

This PEP provides a convention to ensure that Python scripts can continue to be portable across *nix systems, regardless of the default version of the Python interpreter (i.e. the version invoked by the python command).

python2 will refer to some version of Python 2.x

python3 will refer to some version of Python 3.x

python should refer to the same target as python2 but may refer to python3 on some bleeding edge distributions

You have Python 2 and Python 3 installed, so the python command refers to python2. If you want Python 3, do it explicitly with the python3 command.

You have few options

In your bash ~/.bash_profile add alias python='python3'
Instead of using python command use python3 instead.
Install python3 via homebrew
