Well, I think the whole discussion has basically been about personal preference. OTOH, but if you call the function a few million times, you might find the cost of try/except to be something that you would rather not incur -- it might become a performance issue rather than a personal choice issue. On the other OTHER hand, if you call the function a few billion times, performance weighs more heavily in favor of the closure approach rather than the object approach, since local variable lookup is so much cheaper.
Indeed. I was surprised to find your __getattr__ approach faster than the try/except approach (about 20% on my machine). I'll have to think about that for future situations like this.
My main point, though, was using __call__, and not some weird _ method. ;) ~Ethan~ -- http://mail.python.org/mailman/listinfo/python-list
