title: Upgrading Python in Virtual Env
body: <p>I have python 2.6.1 installed on Mac OS X. I wanted to play around with python 3.2, so i created a virtual enviromant using </p>
  
  <p><code>virtualenv python3.0</code></p>
  
  <p>and then activated it using </p>
  
  <p><code>source python3.0/bin/activate</code></p>
  
  <p>if I update the python in the virtualenv will it leave my system python untouched? If yes, do I just install python 3 using pip install?</p>
