title: Python: how to edit an installed package?
body: <p>I installed some package via <code>pip install something</code>. I want to edit the source code for the package <code>something</code>. Where is it (on ubuntu 12.04) and how do I make it reload each time I edit the source code and run it?</p>
  
  <p>Currently I am editing the source code, and then running python setup.py again and again, which turns out to be quite a hassle.</p>
