The Describe function returns the following properties for Datasets.
Dataset properties are available in many types of Describe objects.

Muestra de código
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))
