Resumen
The Describe function returns the following properties for datasets.
Dataset properties are available in many types of Describe objects.
Propiedades
| Propiedad | Explicación | Tipo de datos |
| canVersion (Sólo lectura) | Indicates whether the dataset can be versioned. | Boolean |
| changeTracked (Sólo lectura) | Indicates whether the dataset is change tracked. | Boolean |
| datasetType (Sólo lectura) | Returns the type of dataset being described.
| String |
| DSID (Sólo lectura) | The ID of the dataset. | Integer |
| extent (Sólo lectura) | The Extent object. Nota:extent is available for spatial datasets only. | Extent |
| isArchived (Sólo lectura) | Indicates whether the dataset has been archived. isArchived is only supported for an enterprise geodatabase. | Boolean |
| isVersioned (Sólo lectura) | Indicates whether the dataset is versioned. | Boolean |
| MExtent (Sólo lectura) | A space-delimited string (MMin, MMax). Nota:MExtent is available for spatial datasets only. | String |
| spatialReference (Sólo lectura) | Returns the SpatialReference object for the dataset. Nota:spatialReference is available for spatial datasets only. | SpatialReference |
| workspace (Sólo lectura) | Returns a Describe object with the properties of the input dataset's workspace. See Workspace properties for specific workspace-related Describe details. Nota:Use this property to determine workspace properties for many data types including: layers, and feature classes in a geodatabase that may or may not be in a feature dataset. | Describe |
| ZExtent (Sólo lectura) | A space-delimited string (ZMin, ZMax). Nota:ZExtent is available for spatial datasets only. | String |

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)))
