New submission from the mulhern: The problems is that it is quite possible to define a property using @property in a class and then later to realize that it really ought to be a class method, not an instance method. But then, if you change it to a class method, using @classmethod annotation, the @property annotation will fail to work. If you are a pedantic person, and name your properties differently than you name your methods, you have to: 1) Change all uses of this former property back to method invocations, with a "()" 2) Change the name, so it now reflects that it is an actual function, not a property any longer.
I think an @classproperty and an @staticproperty decorator would take this problem away. An alternative would be to make it possible to chain @property and @classmethod. I know that this is sort of doable for ABC.abstractproperty which is now deprecated in favor of @property combined with @ABC.abstractmethod. This would be ideal, but I can not pretend to know if it would be possible. Also, I suspect that the order would matter as it does for ABC as described in http://bugs.python.org/issue16267. ---------- components: Library (Lib) messages: 211416 nosy: the.mulhern priority: normal severity: normal status: open title: Want to make a class method a property by combining decorators type: enhancement versions: Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20659> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
