1. The statement *item is roughly the same thing as (item[0], item[1], item[n])
No, it's not -- that would make it equivalent to tuple(item), which is not what it means in any of its existing usages. What it *is* roughly equivalent to is item[0], item[1], item[n] i.e. *without* the parens, whatever that means in the context concerned. In the context of a function call, it has the effect of splicing the sequence in as if you had written each item out as a separate expression. You do have a valid objection insofar as this currently has no meaning at all in a comprehension, i.e. this is a syntax error: [item[0], item[1], item[n] for item in items] So we would be giving a meaning to something that doesn't currently have a meaning, rather than changing an existing meaning, if you see what I mean. -- Greg _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
