FWIW my attempt at explaining decorators is here: http://personalpages.tds.net/~kent37/kk/00001.html > I've only been using Python for a couple of years now, but my > experience so far is the same as yours: decorators make my head hurt. > Even in the Dr. Dobbs article, the examples seem horribly contrived. It's hard to find a simple example of decorators that is not contrived. The real-world cases are often too complex for an introduction. I cite a few examples in my article. Some other examples: Django's login_required decorator: http://docs.djangoproject.com/en/dev/topics/auth/#the-login-required-decorator In the standard lib, contextlib.contextmanager makes it easy to define context managers (objects that work with the 'with' statement): http://docs.python.org/library/contextlib.html#contextlib.contextmanager and functools.wraps helps to make well-behaved decorators ;-) http://docs.python.org/library/functools.html#functools.wraps I told you it was hard to find simple examples!)
