Using property() on classmethods

Question

I have a class with two class methods (using the classmethod() function) for getting and setting what is essentially a static variable. I tried to use the property() functi

Answer 1

Here is my solution that also caches the class property

class class_property(object):
    # this caches the result of the function call for fn with cls input
    # use this as a decorator on function methods that you want converted
    # into cached properties

    def __init__(self, fn):
        self._fn_name = fn.__name__
        if not isinstance(fn, (classmethod, staticmethod)):
            fn = classmethod(fn)
        self._fn = fn

    def __get__(self, obj, cls=None):
        if cls is None:
            cls = type(obj)
        if (
            self._fn_name in vars(cls) and
            type(vars(cls)[self._fn_name]).__name__ != "class_property"
        ):
            return vars(cls)[self._fn_name]
        else:
            value = self._fn.__get__(obj, cls)()
            setattr(cls, self._fn_name, value)
            return value
