title: Where is the python path set when I don't have a .bash_profile?
body: <p>I am running ubuntu, and I don't have a .bash_profile.</p>
  
  <p>So my question is, where exactly is my python path set then?</p>
  
  <p>How can I see what the current python path is, doing:</p>
  
  <pre><code>$PYTHON_PATH
  </code></pre>
  
  <p>doesn't return anything?</p>
