ListFeatureClasses

Zusammenfassung

Lists the feature classes in the workspace, limited by name, feature type, and optional feature dataset. A Python List is returned from the function.

Beschreibung

The workspace environment must be set first before using several of the List functions, including ListDatasets, ListFeatureClasses, ListFiles, ListRasters, ListTables, and ListWorkspaces.

Syntax

ListFeatureClasses ({wild_card}, {feature_type}, {feature_dataset})
ParameterErläuterungDatentyp
wild_card

Der Platzhalter schränkt die zurückgegebenen Ergebnisse ein. Wenn kein Platzhalter angegeben wird, werden alle Werte zurückgegeben.

String
feature_type

The feature type to limit the results returned by the wild card argument. Valid feature types are:

  • AnnotationOnly annotation feature classes are returned.
  • ArcOnly arc (or line) feature classes are returned.
  • DimensionOnly dimension feature classes are returned.
  • EdgeOnly edge feature classes are returned.
  • JunctionOnly junction feature classes are returned.
  • Label Only label feature classes are returned.
  • LineOnly line (or arc) feature classes are returned.
  • MultipatchOnly multipatch feature classes are returned.
  • NodeOnly node feature classes are returned.
  • PointOnly point feature classes are returned.
  • PolygonOnly polygon feature classes are returned.
  • PolylineOnly line (or arc) feature classes are returned.
  • RegionOnly region feature classes are returned.
  • RouteOnly route feature classes are returned.
  • TicOnly tic feature classes are returned.
  • All All datasets in the workspace. This is the default value.

(Der Standardwert ist All)

Codebeispiel

ListFeatureClasses example

Copy shapefiles to a geodatabase.

import arcpy
from arcpy import env
import os

# Set the workspace for the ListFeatureClass function
#
env.workspace = "c:/base"

# Use the ListFeatureClasses function to return a list of 
#  shapefiles.
#
fcList = arcpy.ListFeatureClasses()

# Copy shapefiles to a file geodatabase
#
for fc in fcList:
    arcpy.CopyFeatures_management(
        fc, os.path.join("c:/base/output.gdb", os.path.splitext(fc)[0]))
