I am trying to perform an operation on a string field with a condition that it contains data. Referencing
None with Python does not appear to work when the field is nullable and contains
<Null> for its data. Am I missing something? I have tried
"Null" as well. What do?
The code, for kicks:
def apt(addr,aptnum): if aptnum != None: a = addr.split(aptnum,1)[-1] return a else: return addr
Update: It would appear that my problem is that field calculations are not processing on any rows where a
null column is tested. That is outside the scope of this question, however, so I will leave it for the time being.
