Not sure if this is feasible or not. The implementation/example below is dummy, FYI.

I have a Python class, Person. Each person has a public first name and a public last name attribute with corresponding private attributes – I’m using a descriptor pattern to manage access to the underlying private attributes.

I am using the descriptor to count the number of times the attribute is accessed as well as obtain the underlying result.

class AttributeAccessCounter:
    def __init__(self):
        self._access_count = 0

    def __get__(self, instance, owner):
        self._access_count += 1
        return getattr(instance, self.attrib_name)

    def __set_name__(self, obj, name):
        self.attrib_name = f'_{name}'

    @property
    def counter(self):
        return self._access_count


class Person:
    first = AttributeAccessCounter()
    last = AttributeAccessCounter()

    def __init__(self, first, last):
        self._first = first
        self._last = last

From an instance of the class Person, how can I access the _access_count or property counter?

john = Person('John','Smith')
print(john.first) # 'John'
print(john.first.counter) # AttributeError: 'str' object has no attribute 'counter'
