No, no no no. You misunderstood the approach that I think most of us were on, which is import library Library = library.Library() Library.SPAMPARAM = 'jam' i_want_spam_now = Library.make_spam(99) One extra line for the import, plus one for each default setting they want to override (which you're stuck with either way). I suppose you could even pass all those overrides in to the Library __init__, but now we're in the weeds. And again, for the ones that don't want to mess with the default params, you can have: import library.defaultinstance as Library -- Rob Gaddi, Highland Technology -- www.highlandtechnology.com Email address domain is currently out of order.
