Working with Group layers through Python

 This tool will be helpful in accessing the Trace Managaement Results

TOOL USED:  arcpy.mapping

Python script will be deployed in the ARC Toolbox to create the Conversion Tool

WORKING OF THE TOOL:

This tool will iterate through each layer in the group layer and perform operation on each layer for every iterations

PROCEDURE:

·         Create a New Script tool in your toolbox of your ArcCatalog

·         Set any empty python code file as source file in which you are going to write your script

·         Set Output layer as input parameter and group layers as the data Type

·         Copy the following code into your python code file

import arcpy

from arcpy import env

arcpy.env.overwriteOutput=1

outputgrouplayer=arcpy.GetParameter(0)

#Assign the output group layer to a variable, to be used later

lyrs =outputgrouplayer

print lyrs

#Create a Mapping Layer out of the Group Layer

groupLayer = arcpy.mapping.Layer(lyrs)

#Get a list of all the mappping layers, the first return will be the Group Layer itself

newLyrs = arcpy.mapping.ListLayers(groupLayer)

#Iterate through all of the Layers (mapping layers)

for lyr in newLyrs:

    #Because the first return is the group layer itself, we check for this, and move on

    if not lyr.isGroupLayer:

        print "Layer name is: {0}. Count is: {1}.".format(lyr.name, str(arcpy.GetCount_management(lyr)))

• This will print the layer name and count of feature for every layer in the Group layer inputted
•  Run the script tool and target your group layer as the input in the parameter box. Click on Ok
• Now it is Party time. Happy Coding
