I'd call that a code-smell. If I saw that in code, I'd think long and hard about why it was there and if I could eliminate the names a...f and just work directly with the list. But if you really do need it, I think the simplest and best way is to use the technique Stefan suggested: a, b, c, d, e, f = (list + [None]*6)[:6] provided list is short. If you fear that list might be huge and copying it will be prohibitively expensive: a, b, c, d, e, f = (list[:6] + [None]*6)[:6] -- Steven -- http://mail.python.org/mailman/listinfo/python-list
