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))
