It's not, really -- unless other places where a tuple can appear were changed likewise, e.g. x = would have to assign an empty tuple to x, etc. > But you may also have several > zero-dimensional arrays, that is, single values - for example, the > income tax rate. But *why* do these need to be 0-dimensional arrays rather than just scalars? I'm having trouble seeing any use for such a distinction. I'm particularly unconvinced by the spreadsheet argument. In that context, I'd say that everything is a 2-D array, and a single cell is a 1x1 2-D array, not a 0-D array. -- Greg _______________________________________________ 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
