What is the best way to detect a TypeNone field in a tuple, or in a list? I am accessing a MySQL database using the MySQLdb Python interface... this interface returns a tuple object type in response to SQL SELECT statements. My understanding of the MySQLdb interface is that NULL database values are returned as a Python 'None' object.
Because I need to create some work fields based on the contents of the database I am doing so by copying the tuple to a list object and then calculating these work fields as needed. My problem is that I need to be able to detect the Python 'None' objects and convert them to an integer zero value field to enable my calculations to work. I'm new to Python so I'm sure I'm overlooking something simple – but what is the easiest way to do a logical test for the existence of a TypeNone field? -- http://mail.python.org/mailman/listinfo/python-list
