title: How can I tail a log file in Python?
body: <p>I'd like to make the output of tail -F or something similar available to me in Python without blocking or locking. I've found some really old code to do that <a href="http://code.activestate.com/recipes/436477-filetailpy/">here</a>, but I'm thinking there must be a better way or a library to do the same thing by now. Anyone know of one?</p>
  
  <p>Ideally, I'd have something like <code>tail.getNewData()</code> that I could call every time I wanted more data.</p>
