What is the correct format for finding perimeter as an expression for arcpy.I was able to use expression !shape.Area! to find the area of my polygon.However when I use the expression !shape.Perimeter! I get invalid expression.I've tried the following expressions;
!shape.Perimeter!@KILOMETERS!!shape.geodesicPerimeter!!shape.geodesicPerimeter@KILOMETERS!These do not work. I was able to find the perimeter using the attribute table and right clicking and going to calculate geometry. Therefore I know its possible, just I require the syntax for my python code.
My python code that works for area looks like this.
arcpy.CalculateField_management("Iceberg","Area","!shape.geodesicArea@SQUAREKILOMETERS!","PYTHON_9.3","#")However my python code for perimeter is not working and it looks like this;
arcpy.CalculateField_management("Iceberg","Area","!shape.geodesicperimeter@KILOMETERS!","PYTHON_9.3","#")I must be missing something, and I've looked at some examples, and have also done, X and Y coordinates, all work, but I cannot get my perimeter to work
