Python question regarding Null Values

MattFolley__DOIT_ — Thu, 29 Jan 2015 15:02:40 GMT

Trying to calculate a field within a model builder process, and I am getting returns I was not expecting. I am trying to have the Null values calculated as 0s (Number field). Now, the non-Null values are being calculated to 0s and leaving the Null values.

Hello Matt,

You probably need to add an else in there and check for the field equals <null>. Something like:

expression:

nullfill(!FREQUENCY!)

codeblock:

def nullfill(value):
    if value == None:
        return 0
    else:
        return value
