I want to make a loop where if a column is empty in a row to do something else. The problem is that it can't determine the empty row. I tried as null, na , '',' ' and with double quotes and nothing.

for i in t_list:
    with arcpy.da.SearchCursor(i, ["name","num"]) as cur:
        for row in cur:
            if row[1] is not "''":


nog1, num = '1'
nog2, ''

And it returns even the the empty rows

To check for not na/none use:

if row[1] is not None

To check for both None and empty string use:

if row[1] not in ('', None)

Or simply:

if row[1]

Which will be true if value is not empty or None:

a = ''
if a:
    print('Not empty')
a = None
if a:
    print('Not None')
a = 'hello'
if a:
