title: Log Analysis in Python
body: <p>For our internal monitoring process, I want to find out how many exceptions have taken place on a particular day. We want to extract the information from the log file of our application (Pylons project).</p>
  
  <p>I want to do this in Python itself. I am aware that I can write a script which will do the offline processing on the log for counting the number of exceptions (and possibly other information related to the exception as well).</p>
  
  <p>I want to ask whether there is already some library which I can use to do log file analysis in Python or what is the best way to do this? </p>
