ListFeatureClasses method
Release 9.3 Last modified January 19, 2010	Print all topics in : "Properties and Methods"

Note: This topic was updated for 9.3.1.

Lists all feature classes from the selected workspace. Specifying search conditions (wildcard) and a feature type limits the results. The workspace must be specified before using any of the List methods except ListFields and ListIndexes.

Returns a Python List that will contain the names of the feature classes under the location specified by the workspace environment setting

NOTE: The content below describes the use of ListFeatureClasses using a 9.3-version geoprocessor. When using a 9.2-version geoprocessor, ListFeatureClasses returns an enumeration instead of a Python List. For more information, see Differences between geoprocessor versions.

Syntax

object.ListFeatureClasses({wildCard} As String, {FeatureType} As String) As Python List

{} = optional

Part	Description
object	The instantiated geoprocessing object.
wild card	Optional. Combination of * and characters that helps to limit the results. The asterisk is the same as saying ALL. If no wildcard is specified, all feature classes in the workspace will be returned.
FeatureType	Optional. Feature type keyword that limits the returned feature classes. Valid feature types for this method are ANNOTATION—Only annotation feature classes will be returned. ARC—Only arc (or line) feature classes will be returned. DIMENSION—Only dimension feature classes will be returned. LABEL—Only label feature classes will be returned. LINE—Only line (or arc) feature classes will be returned. NODE—Only node feature classes will be returned. POINT—Only point feature classes will be returned. POLYGON—Only polygon feature classes will be returned. REGION—Only region feature classes will be returned. ROUTE—Only route feature classes will be returned. TIC—Only tic feature classes will be returned.

Examples

This script shows how the ListFeatureClasses method can be used to create a list object that contains the names of all the feature classes in a workspace.

import arcgisscripting
import os
gp = arcgisscripting.create(9.3)

gp.workspace = "d:/MyData"
out_workspace = "d:/MyData/Results"
clip_features = "d:/MyData/TestArea/Boundary.shp"

# Get a list of feature classes in the workspace.
#
fcs = gp.ListFeatureClasses()

for fc in fcs:
    # Set the outputname for each output to be the same as the input.
    #
    output = out_workspace + os.sep + fc

    # Clip each input feature class in the list.
    #
    gp.clip_analysis(fc, clip_features, output, 5)
