version - How to: Macports select python

Question

When I enter:

port select --list python

This is the result:

Available versions for python:
    none
    python25 (active)
    python25-apple
    python26-apple
    python27
    python27-apple

I thought when I use python I would be using version 2.5. Instead when I enter "python", version 2.7 seems to be active. How do I change that to version 2.5?

Python 2.7.1 (r271:86832, Jun 16 2011, 16:59:05) 
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin

Use

osx$ port select --list python

to list your available Python installations.

Then use the "--set" option to "port select" to set the port you wish to use.

osx$ sudo port select --set python python27
