title: run python script directly from command line
body: <pre><code>#!/usr/bin/env python
  </code></pre>
  
  <p>I put that at the top of a script.  I've seen that should make the script runnable from the command line without the need for <code>python programname.py</code>.  Unless I'm misunderstanding I should be able to use <code>programname.py</code> as long as I have the above line at the top of the script.  Is this correct?  </p>
  
  <p>It isn't working for me I just get an error indicating that I would have to use <code>python</code> at the beginning of the 'call'.</p>
