title: Human-readable datetime interval to datetime.timedelta in Python?
body: <p>I find myself needing to specify a timespan in a python configuration file a lot.  </p>
  
  <p>Is there a way that I can specify a more human readable timeframe (similar to PostgreSQL's Interval syntax) in a python configuration file with stdlib?  Or will this require a 3rd party lib?</p>
  
  <p><strong>Clarification</strong>  I'm not looking for anything in the <code>ConfigParser.ConfigParser</code> stdlib API specifically.  I guess what I really need is a way to go from human readable date/time interval to <code>datetime.timedelta</code> value.</p>
