The unicode object IS subscriptable. It is a unicode string which has
characters.
The value None is not subscriptable. It probably means that you have a
NULL value in your database.
Try the following:
def nulltoemptystr(value):
if value is None:
return "<EMPTY>"
else:
return value[:10]
print template % (ID, IID, nulltoemptystr(Function),
nulltoemptystr(Description),ErrorNumber, StatusCD)
You can also try to do the same in SQL. For example, this works with
FireBird, PostgreSQL and many others:
select coalesce(Function,"") as Function from TableName
instead of
select Function from TableName
But first of all, I would recommend you to go over the Python tutorial.
It explains these things and more.
