Personally I do the following (in its own module). There may be a better 
way, but this is simple and it works:

_theSingleton = None

def getSingleton():
   global _theSingleton
   if not _theSingleton:
      _theSingleton = _Singleton()
   return _theSingleton

class _Singleton:
   def __init__(self, ...):
      ...
