FeatureSet example

Load data into FeatureSet and insert into feature class.

# Loading data to a FeatureSet using cursors 
#  and an in_memory feature class.
#
import arcpy
from arcpy import env

env.overwriteOutput = True

arcpy.ImportToolbox("http://flame7/arcgis/services;BufferByVal", "server")

# List of coordinates
