Here is a snippet from the argparse module: {{{ def parse_known_args(self, args=None, namespace=None): ... # default Namespace built from parser defaults if namespace is None: namespace = Namespace() # < ======= my issue }}}
I subclass from the class of the above snippet. I would like to use a different Namespace class. if the above could would use namespace = self.Namespace() it would be very easy for me to inject a different Namespace class. Yes, I have seen the "namespace" kwarg. This is not the first time I would like the upstream code to make subclassing more fun. Some months ago I asked myself how to call the "self.Namespace()" pattern: http://stackoverflow.com/questions/27571848/name-of-design-pattern-get-class-from-class-level The answer with the most upvotes states it is the Factory method pattern. I prefer "self.Namespace()" to namespace kwargs. What do you think? -- https://mail.python.org/mailman/listinfo/python-list
