factory that captures the usual args, kwargs of instantiation and saves them so multiple copies can be created.

factory.py

from functools import wraps

class Factory(object):
    def __init__(self, cls, *args, **kwargs):
        self._cls = cls
        self._args = args
        self._kwargs = kwargs
    @property
    def instance(self):
        return self._cls(*(self._args), **(self._kwargs))

def f(cls):
    @wraps(cls)
    def init(*args, **kwargs):
        return Factory(cls, *args, **kwargs)
    return init
