Steve The data-structure being returned is a tuple. The tuple is defined by the comma-separator - not the parentheses. Of course, the way you use them (first example) involves "unpacking" after the tuple 'crosses' the equals/assignment. Thus, the answer to your question is a matter of style, and thus the understanding of those who might read the code. FWIW: I leave them out because it is easier on my eyes whilst scanning the line of code. -- Regards, =dn -- https://mail.python.org/mailman/listinfo/python-list
