title: How to install Python 3.1.2 on Mac OS X 10.6.4?
body: <p>Hi there I have downloaded the mac installer here, <a href="http://www.python.org/download/releases/3.1.2/" rel="nofollow noreferrer">http://www.python.org/download/releases/3.1.2/</a> , &amp; installed it. But when I run terminal &amp; type python it says:</p>
  
  <blockquote>
    <p>Python 2.6.1 (r261:67515, Feb 11 2010, 00:51:29)
    [GCC 4.2.1 (Apple Inc. build 5646)] on darwin
    Type "help", "copyright", "credits" or "license" for more information.</p>
  </blockquote>
  
  <p>What I want to know is, is it safe to run Update Shell Profile.command in the Python 3.1 folder ? or should I run python 3.1.2 separately ? If I should run python 3.1.2 separately, how do I do so ? also how do I start IDLE ?</p>
