I want to a method that runs when object reference count is changed. is there a method like the following code ?

class Foo():
    def __method__(self):
        print("ojbect reference count is changed !")

a = Foo()
b = a  # runs __method__ because the reference count is increased
c = b  # runs __method__ because the reference count is increased
del b  # runs __method__ because the reference count is decreased
del c  # runs __method__ because the reference count is decreased

thanks.
