Well, OK, I exaggerated a bit. Multiplication binds stronger than addition in any language I've ever used, so I assume I know that one. But not much beyond that. > if (b >= (-1)): No, I wouldn't use either set of parens their either. But, if I have any doubt at all, I rather than look it up, I just put parens. And my threshold for doubt is pretty low. -- https://mail.python.org/mailman/listinfo/python-list
