Most of the time you probably want to catch either Exception (which excludes GeneratorExit, KeyboardInterrupt and SystemExit) or StandardError (which excludes the above pluse warnings and StopIteration). Only in specific circumstances can you reasonably go finer than that, partly due to the set of exceptions a method may throw seldom being documented, and partly due to duck typing; a parameter which is intended to be a file object could realistically be any object which supports the appropriate methods (e.g. .read()), and there's no guarantee that those methods will have the same set of possible exceptions as a real file object. -- http://mail.python.org/mailman/listinfo/python-list
