Yeah I am having a hard time with this.

I revised my script again using tuples() to access the value:

r = container.view_activity(SystemNetName =
if r == 'active':
 return r
 return 'failed'

it is still returning 'failed' even though if I print r it returns
Somehow, it is not going through that if statement. Can the single
quotes cause a problem?

I think I don't understand.

view_activity is a ZSQL method, right? ZSQL Methods returns 
Shared.DC.ZRDB.Results.Results instances, which are objects that behave 
as a tuple of records, so status is not a record, is (something behaving

like) a tuple of records, it may be a tuple with just one record, but 
still a tuple. status[0] is a "record". For example, if the sql query is

"select foo, bar from baz", you can do status[0].bar to get the bar 
field from the first record and so on.
