在Python中更改对象引用计数时是否运行魔术方法

Question

我想要一个在更改对象引用计数时运行的方法。是否有类似以下代码的方法？

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

感谢。
