I tend to do: (foo, bar, _,_,_) = gen_tuple(stuff) In cases where I decide I just want the bits I don't want. Aside from anything else, if someone is testing things in the interactive prompt, it's clear that the value is ephemeral, the fact it isn't name emphasises it's unimportance and the repetition (in the above case) really makes it clear. It also _looks_ like the value is thrown away as well. And it doesn't clutter up your namespace... Michael. -- http://mail.python.org/mailman/listinfo/python-list
