I thought I was following this but now I'm not sure. Do you mean that if I have a list L that contains an arbitrary number of sublists that I can call zip using: >>> zip(*L) rather than >>> zip(L[0],L[1],...., L[n]) If so I agree. But any time that you use the *[] format it is easier to just put the content of the [] into the zip directly, which is what, I think, Kent is saying? >> zip(*[a, b, ..., x, y, z]) >> can be written more simply as >> zip(a, b, ..., x, y, z) >> >> Kent -- Alan Gauld Author of the Learn to Program web site http://www.freenetpages.co.uk/hp/alan.gauld _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
