Singleton Pattern In Python

  • submit to reddit
class Borg:
    __shared_state = {}
    def __init__(self):
        self.__dict__ = self.__shared_state
What a pythonic way to use Singleton. It uses shared-state
approach where you can actually have many instances as you want
but they all share the same state. See Alex's <a href=>recipe</a>.
>>> b = Borg()
>>> b.x = 1
>>> c = Borg()
>>> c.x
