I want to remove that stack trace...so it looks more clean to a user. What can be done in this case? Well, I don't understand how and from what context you are calling testHook(). My first instinct is to ask, why you can't simply return instead of 'raise' on an abort ? like so ... def testHook(exc): choice = raw_input(Would you like to continue (Y or N): ) if(str(choice).lower() != 'y'): print(You chose not to go ahead. Ok!!\nAborting Now...) print User initiated Abort... return -1 # ...or any other value that makes sense to your app. else: raise exc # re-raise the passed exception In which case, I am assuming testHook() called like this: try: 1 + foo except Exception, e: return testHook(e) or any other way of creating such a hook? Yes. The way I would do this sort of this is by using decorators: def testHook(func): ... def wrap_exception(*args): ... try: ... func(*args) ... except Exception, e: ... choice = raw_input(Would you like to continue (Y or N): ) ... if (str(choice).lower() != 'y'): ... print(You chose not to go ahead. Ok!!\nAborting Now...) ... print User initiated abort ... ... print on recieving %s % e.message ... return ... else: ... print redirect to debugger in this block ... ... return wrap_exception ... @testHook ... def main(a, b): ... return a + b ... main(1, foo) Would you like to continue (Y or N): n You chose not to go ahead. Ok!! Aborting Now... User initiated abort ... on recieving unsupported operand type(s) for +: 'int' and 'str' Here is a good article for introducing decorators: http://www.ibm.com/developerworks/linux/library/l-cpdecor.html HTH, cheers, - steve -- random non tech spiel: http://lonetwin.blogspot.com/ tech randomness: http://lonehacks.blogspot.com/ what i'm stumbling into: http://lonetwin.stumbleupon.com/ ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers

[BangPypers] Help Python framework for report creation (bar graph, pie etc)
Hi all, I'm relatively a newbie to python. But i do read most of the posts in this list. Currently I'm doing a study on developing one reporting framework to pull the data from the database and project in appealing way like pie charts, normal charts, bar graphs etc. Would any body please comment on some good frameworks in python (web based GUI), which is already available on which i can add my customizations. This is to replace one of the reporting frameworks provided by Business Objects Web Intelligence. Any comments on where to start, how to start are much appreciated. Please help. Many Thanks Jins Thomas ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers
