[issue38524] functools.cached_property is not supported for setattr

[hongweipeng]

hongweipeng <hongweichen8888 at sina.com> added the comment:

Is it possible to add an attrname parameter? It is more convenient to use.

class cached_property:
    def __init__(self, func, attrname=None):
        self.attrname = attrname
        ...

cls.age3 = cached_property(age, 'age3')
