title: How to change default Python version?
body: <p>I have installed Python 3.2 in my Mac. After I run <strong>/Applications/Python 3.2/Update Shell Profile.command</strong>, it's confusing that when I type <strong>Python -V</strong> in Terminal it says that <strong>Python 2.6.1</strong>.</p>
  <p>How can I change the default Python version?</p>
