def __new__(cls):

_ try:

_ _ return cls._singleton

_ except AttributeError:

_ _ s = cls._singleton = object.__new__(cls)

_ _ return s

Or you can do:

class _SingletonClass: …

_TheSingleton = _SingletonClass

def SingletonClass():

_ return _TheSingleton

The last one is my preferred solution ;)
