Topology properties example (stand-alone script)

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)
