property inheritance: not able to call properties from parent classes

[TG-Techie]

the code below returns this error:

Traceback (most recent call last):
File "main.py", line 39, in
File "/file_location", line ###, in val
AttributeError: 'super' object has no attribute 'val'

class parent():
    def __init__(self, initval):
        self._val = initval

    @property
    def val(self):
        return self._val

    @val.setter
    def val(self, valin):
        self._val = valin
        print('in parent')

def child(parent):

    @property
    def val(self):
        return super()._val

    @val.setter
    def val(self, valin):
        super().val = valin
        print('in child')

This doesn't work in CPython either.
Maybe this can give some insight: https://stackoverflow.com/questions/13595607/using-super-in-a-propertys-setter-method-when-using-the-property-decorator-r

I tested Example 2 and it works in CircuitPython.

@notro Thanks, this is a complicated issue. Let close it as not an issue specific to CircuitPython.
