But it's the same thing that's wrong with having one variable called 'q', when that variable would be better called 'invoice' because it's iterating over your invoices, or 'item' when it's iterating over the lines of one invoice. Python doesn't stop you from doing that; it's not the language's job to enforce useful variable names. ChrisA -- http://mail.python.org/mailman/listinfo/python-list
