title: How to display Python file header description
body: <p>I was wondering if you knew how to run a python file to only display the file description. 
  For example I have these lines on the top of my python program.</p>
  
  <pre><code>"""
  ===================================================
      test.py
      sphchow
  
      Description
  ====================================================
  """
  </code></pre>
  
  <p>I want to be able to run it so it displays this. But also have the ability to run the program normally. I tried searching around and could only find information like <code>__docstring__</code> I think I'm not using the right key words?</p>
