Dataset properties example (stand-alone script)

The following stand-alone script displays dataset properties for a shapefile. 

import arcpy

# Create a Describe object from the shapefile
#
desc = arcpy.Describe("C:/temp/xy.shp")

# Print dataset properties
#
print("Dataset Type: {0}".format(desc.datasetType))
print("Extent:\n  XMin: {0}, XMax: {1}, YMin: {2}, YMax: {3}".format(
    desc.extent.XMin, desc.extent.XMax, desc.extent.YMin, desc.extent.YMax))
print("MExtent: {0}".format(desc.MExtent))
print("ZExtent: {0}".format(desc.ZExtent))

print("Spatial reference name: {0}:".format(desc.spatialReference.name))
