Actual behavior

the singleton fuc is :

def singleton(cls, *args, **kw):
    instances = {}

    def _singleton():
        key = str(cls) + str(os.getpid())
        if key not in instances:
            instances[key] = cls(*args, **kw)
        return instances[key]

    return _singleton

Expected behavior

I think it'is :

def singleton(cls):
    instances = {}

    def _singleton(*args, **kw):
        key = str(cls) + str(os.getpid())
        if key not in instances:
            instances[key] = cls(*args, **kw)
        return instances[key]

    return _singleton
