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 several tries, I still could not add a new row to the table.

arcpy arcgis-10.0 cursor

  To add a new row you need to be using an InsertCursor. If you are using ArcGIS Desktop 10.0 then you cannot be using arcpy.da because it did not exist until 10.1. What version are you using?
