Having it return NoneType there seems a strange thing to do, as have a None field makes no sense. Why would you have a column that can only contain the value None? What is returning NoneType at that point supposed to signify? If it's supposed to signify that the value is NULL, I think the above code is a very strange way of handling that. get_type(field) should reasonably return the type of the column, not the type of the value you got, as that would be just type(field) and doing type(field)(field) is a bit pointless. :-) //Lennart _______________________________________________ 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
