title: Python Versions on Mac
body: <p>I'm working on Mac Os 10.7 (Lion) and I have some questions:</p>
  
  <ol>
  <li>What is the pre-installed version of python on Lion?</li>
  <li>I've been working on this computer for some time now, and i've installed lots of software in order to do college work many times I didn't know what I was really doing. The thing is: now I hava on the /Library/Frameworks/Python.framework/Versions/ a folder called "7.0" I'm pretty sure there no python version 7. Is this folder native or a third-part program installation. Can I delete it? (it's using 1 Gb on disk).</li>
  <li>Where is located the original python that comes with mac os?</li>
  <li>I've choose Homebrew as my package manager, is there a easy way to manage python versions with it?  </li>
  </ol>
