Heh. From the original Usenet posting that suggested the capability that was added in the form of "setdefault": | I suggest a minor change: another optional argument to | "get" so that | | dict.get(item,default,flag) | | is equivalent to | | if dict.has_key(item): | VALUE IS dict[item] | else: | if flag: dict[item] = default <-- This is all that's new | VALUE IS default | | but presumably more efficient. The response was a chorus of people saying "Not a bad idea, but that flag sucks. It needs a separate method." :-) -- g _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
