I know it won't generate the list of items from the forward dict, but I was thinking of the list generated by the list comprehension, passed as the argument to the reverse dict constructor. That's the throw-away list I was thinking of (see Tim Delaney's response to my post). -- http://mail.python.org/mailman/listinfo/python-list
