At least show your import statements, so we might have a chance at guessing. I'll assume the db stands for database, but what database, or what library??? if it really is a database question, and you specify what library you're using, then maybe somebody who uses that will jump in.

Do you mean you get an exception? If so, paste it into a message, the full traceback. Or you mean it returns the wrong data? Or it crashes your OS? My first guess would be that those slashes are causing syntax errors. But if that's a bug in your OS's copy/paste, then I'd say you have indentation problems. Or maybe these are not just functions, but methods inside a class. And in that case, I might guess that you're missing the self argument, and therefore getting an exception of wrong number of arguments. -- DaveA -- http://mail.python.org/mailman/listinfo/python-list
