changing python path on mac?!

Question

I would like to change PATH from Python 2.6.1 to 3.1.2. I have both versions installed on my computer but when I type python --version in the terminal I get Python 2.6.1 so thats the current version its "pointing" to. Now if I type Python3.1 it changes the current version to the one I want to use, though the PATH is still 2.6.1. Downloaded with the Python 3.1 package comes a Update Shell Profile.command, so when I run it and then run nano ~/.bash_profile it says there: Setting PATH for Python 3.1 the orginal version is saved in .bash_profile.pysave PATH="/Library/Frameworks/Python.framework/Versions/3.1/bin:${PATH}" export PATH.

Does this mean that I have changed the PATH or does it just give me instructions how to?!

Regards

Answer 1

PATH="/Library/Frameworks/Python.framework/Versions/3.1/bin:${PATH}" 
export PATH

This will append the Python directory to the path.

If this is part of ~/.bash_profile, this will append the Python path on each startup.
