Junction Source Properties Example

Displays information for junction sources in the network dataset.

# Name: NDSJunctionSourceProperties_ex01.py
# Description: Print the information about the junction sources defined for the
#              network dataset

import arcpy
import sys

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

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

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

#Get all the junction sources for the network dataset
junctions = desc.junctionSources

if not junctions:
    print(" %*s" % (justify, "(No junction sources)"))
    sys.exit(0)

for junction in junctions:
    print(" %*s: %s" % (justify, "Source Name" , junction.name))
    print(" %*s: %s" % (justify, "Source ID" , str(junction.sourceID)))
    print(" %*s: %s" % (justify, "Source Type", junction.sourceType))
    print(" %*s: %s" % (justify, "Element Type", junction.elementType))
    print(" %*s: %s" % (justify, "Elevation Field",
                        junction.elevationFieldName))
    print(" ")
