iterate over class properties?

[Gribouillis]

It would perhaps be better to unpack my function a little. I don't claim it is the best way to do this, but I'm going to explain the following code

import inspect

def _get_names(cls):
    for tp in inspect.getmro(cls):
        for name, value in vars(tp).items():
            if isinstance(value, property):
                yield name

_register = {}

def property_names(cls):
    if cls not in _register:
        _register[cls] = sorted(set(_get_names(cls)))
    return _register[cls]


def add_property_names(cls):
    cls.property_names = classmethod(property_names)
    return cls

if __name__ == '__main__':
    class A:
        pass

    class B(A):
        @property
        def foo(self):
            return 0
        
    class C(B):
        @property
        def bar(self):
            return self._bar
        
        @bar.setter
        def bar(self, value):
            self._bar = value

    add_property_names(A)

    a = A()
    print(a.property_names())
    c = C()
    print(c.property_names())
    cc = C()
    print(cc.property_names())
