Neither, the most Pythonic way IMHO is to use a dictionary and possibly combine with Pythons variable arguments syntax as described in section 4.7.3/4 of the official tutor. > I personally think the latter would look a lot cleaner once the number of > options got up to around a half dozen, but I usually see the "large number > of parameters" style in other people's code. Classes without behaviour are really just glorified dictionaries so I prefer to use a dictionary. The **args mechanism provides a good way to pass these to functions.
