check the field is empty and then add a new row with zeros

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;

I created a table with three fields but there are no values in these fields. Here is the screenshot of these fields.

I want to add a new row with zeros for all these three fields. Here is my code.

with arcpy.da.UpdateCursor(selectionname,("OBJECTID","FREQUENCY","SUM_Shape_Area")) as cursor:

for row in cursor:

   if row[0] == None:

      row[0] = 0

      cursor.updateRow(row)

   else:

      print selectionname + " is not empty"

Selectionname is my table, a parameter defined prior to this part of my code. After serveral tries, I still could not add a new row to the table.

python arcgis-10.0
