class MyProperty:
    def __init__(self, fget = None, fset = None, fdel = None):
        self.fget = fget
        self.fset = fset
        self.fdel = fdel

    def __get__(self, instance, owner):
        return self.fget(instance)

    def __set__(self, instance, value):
        self.fset(instance, value)

    def __del__(self, instance):
        self.fdel(instance)


class C:
    def __init__(self):
        self._x = None

    def getX(self):
        return self._x

    def setX(self,value):
        self._x = value

    def delX(self):
        del self._x

    x = MyProperty(getX, setX, delX)
