Network Directions Attribute Mapping Properties example

Print the network dataset's directions attribute mapping properties.

# Name: NDSDirectionsAttributeMapping_ex01.py
# Description: Print information about the directions attribute mappings
#              for the network dataset.

import arcpy
import sys

network = r"C:/Data/NetworkDatasetWithDirections.gdb/Transportation/Streets_ND"

# Create Describe object for the network dataset
desc = arcpy.Describe(network)

# If the directions are not set for the network dataset, exit
if not desc.supportsDirections:
    print("No direction information")
    sys.exit()

# Get all the network's directions properties
directions = desc.directions

# Loop through the attribute mappings
if hasattr(directions, "attributeMappings"):
    attrMappings = directions.attributeMappings
    for mapping in attrMappings:
        print("\nKey:", mapping.key)
        print("Attribute:", mapping.attribute)
else:
    print("Network dataset does not contain directions attribute mappings.")
