Ok I give up you have convinced me. Of what I am not sure ;) Anyway I have always viewed : a,b,c= (1,2,3) as unpacking a tuple and : (a,b,c) = (1,2,3) as creation of a tuple It was a false assumption, I have used Python for years and have never written an unpacking as: (a,b,c) = (1,2,3) I have always put parens around my tuples I always thought that a tuple was a parens with at least one comma ;) It is just not something I have done, it seems counter to my thinking , till I read from Bengt it is the commas that make the tuple not the parens. It all makes sense now, but if they are not needed I think they that should be avoided for clarity. Steve thanks for your time. I always learn a little from you ;) M.E.Farmer
