title: changing python path on mac?
body: <p>I would like to change my <code>PATH</code> from Python <code>2.6.1</code> to <code>3.1.2</code>. I  have both versions installed on my computer, but when I type <code>python --version</code> in the terminal I get Python <code>2.6.1</code>. So, thats the current version it's &quot;pointing&quot; to. Now if I type <code>python3.1</code> it loads the  version I want to use, although the <code>PATH</code> is still pointing to <code>2.6.1</code>. Downloaded along with the Python 3.1 package comes an <code>Update Shell Profile.command</code> - when I run it and then run <code>nano  ~/.bash_profile</code> it says:</p>
  <blockquote>
  <p>Setting PATH for Python 3.1 the orginal version is saved in .bash_profile.pysave
  PATH=&quot;/Library/Frameworks/Python.framework/Versions/3.1/bin:${PATH}&quot;
  export PATH.</p>
  </blockquote>
  <p>Does this mean that I have changed the <code>PATH</code>, or does it just giving me instructions how to?</p>
