As the others already explained to you there is no way to archive your
goal with an assignment to a local or global variable. But you can
follow a different approach:
class Scene(object):
 def __setattr__(self, name, value):
 super(Scene, self).__setattr__(name value)
 if isinstance(value, SceneObject):
 value.name = name
 value.scene = self
class SceneObject(object):
 pass
class Cube(SceneObject):
 pass
scene = Scene()
scene.cube1 = Cube()
Have fun!
