Turn Source Properties example

Displays information for turn sources in the network dataset.

# Name: NDSTurnSourceProperties_ex01.py
# Description: Print the information about the turn sources defined for the 
#              network dataset

import arcpy
import sys

# Set workspace
arcpy.env.workspace = "C:/Data/SanFrancisco.gdb/Transportation"

#Create a Describe object from the network dataset
desc = arcpy.Describe("Streets_ND")

justify = 35
print ("------- Turn sources") 

#Get all the turn sources for the network dataset
turns = desc.turnSources

#Not all network datasets can have turn sources.
if not turns:
    print ("%*s" % (justify, "(No turn sources)")) 
    sys.exit(0)

for turnSource in turns: 
    print ("%*s: %s" % (justify, "Source Name" , turnSource.name)) 
    print ("%*s: %s" % (justify, "Source ID" , str(turnSource.sourceID))) 
    print ("%*s: %s" % (justify, "Source Type", turnSource.sourceType))
    print ("%*s: %s" % (justify, "Element Type", turnSource.elementType))
    print (" ")
