No, that's not possible. What you could do instead is to create a singlton
that you use to store the values in, instead of the module directly. Like
this (untested):


class ModuleState(object):
   # borg pattern - why not...
   _shared_state = {}
   def __init__(self):
       self.__dict__ = ModuleState._shared_state

   def __setattr__(self, name, value):
       setattr(self, name, "hello")

state = ModuleState()

Then you do

state.test = 5
