title: Where to find python-interpreter error codes?
body: <p>I have a python application that communicates with a PHP application.
  Right now, I have defined error codes on both sides so they match (i.e. we can detect the python-side failures in PHP and react accordingly).</p>
  
  <p>My problem comes from python being an interpreted language, here is why : 
  If the code has a syntax problem, then the interpreter will return error codes.
  But these interpreter error codes will be indistinguishable from the application errors.</p>
  
  <p>I am not in charge of the python code, but I was asked to be able to detect eventual python interpreter failures so I can notify the end user using PHP.</p>
  
  <p>Because of that, I need to find a list of the interpreter return codes when malfunctionning.
  I failed to find this information on both google, python doc, and man page.</p>
  
  <p>Does anybody have/know where to find this information ?
  (also, if you have any other ideas on how to get around this problem, I'd be happy to hear them)</p>
  
  <p>Thanks in advance !</p>
