I presume this is more like: obj = SomeObject() func(**obj) ie making the object behave in a dict-like way. I can't remember how this is implemented, but you can create the necessary methods to have your object produce whatever it likes. All you need to do is subclass collections.abc.Mapping, and implement __len__, __iter__, and __getitem__. Pretty easy. - Alan -- https://mail.python.org/mailman/listinfo/python-list
