title: How to fully revert Python to factory settings on Mac
body: <p>I was looking for this information for a while, but as additional packages and python versions can be installed through <code>homebrew</code> and <code>pip</code> I have the feeling that my environment is messed up. Furthermore a long time ago, I had installed some stuff with <code>sudo pip install</code> and as well <code>sudo python ~/get-pip.py</code>.</p>
  
  <p>Is there a trivial way of removing all danging dependencies and have python as it was when I first got the machine, or at least with only the packages that are delivered with the Mac distro?</p>
