What Steven was talking about was to NOT use a class at all. Modules are
objects and have their own namespace. And you can use threading.locals

hi Steven,
can you explain that?I didn't quite get it.
I have a module say 'managerutils' where I have a class
MyManager..
ie,
managerutils.py
--
class MyManager(object):
def __init__(self):
self.myaddresses={}
...
from another main program ,if I call ,
import managerutils
thanks Steven..that was very helpful..thanks a lot

hi
I have been trying out singleton design pattern implementations..I
wrote this,
class Singleton(object):
_instance = None
def __new__(self, *args, **kwargs):
if not self._instance:
self._instance = super(Singleton, self).__new__(self,
*args, **kwargs)
return
