This question has been posed several (many?) times in the past. See the archives for more detail, but basically the answer that is usually given is this: Tuples are intended to be used somewhat like C "structs", or Pascal "records", which is to say they should contain heterogeneous sequences of information for which the concept of ".index()" is fairly meaningless. They are _not_ generally intended to be used as "read-only lists", and that's basically why .index() wasn't defined for them. Another answer that probably follows close on the heels of that one is along the lines of "patches are always welcome", but I honestly don't know if a patch to add this would be accepted. Probably checking Sourceforge for past patches would give an answer, since it seems likely someone has already tried. -Peter -- http://mail.python.org/mailman/listinfo/python-list
