Code sample
The following stand-alone script displays properties for a topology:
import arcpy
# Create a Describe object from a topology.
#
desc = arcpy.Describe("C:/data/moad.gdb/East/ParkZones_topology")
# Print some topology properties
#
print("%-27s %s" % ("ClusterTolerance:", desc.clusterTolerance))
print("%-27s %s" % ("ZClusterTolerance:", desc.ZClusterTolerance))
print("%-27s %s" % ("FeatureClassNames:", desc.featureClassNames))
print("%-27s %s" % ("MaximumGeneratedErrorCount:", desc.maximumGeneratedErrorCount))
