I assume you are asking, "Why do these features exist? What makes them useful? When would I use them?" For that, you should re-read the documentation and discussion surrounding them. The short answer is that the above makes your job, as a programmer easier. It's easier because you have to write less code, read less code, and your code has fewer bugs. -- http://mail.python.org/mailman/listinfo/python-list
