ListDatasets

サマリ

Lists all of the datasets in a workspace. Search conditions can be specified for the dataset name and dataset type to limit the Python List that is returned.

説明

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

構文

ListDatasets ({wild_card}, {feature_type})

パラメータ	説明	データ タイプ
wild_card	ワイルドカードを使用して、返される結果を絞り込むことができます。ワイルドカードを指定しない場合は、すべての値が返されます。	String
feature_type	The feature type to limit the results returned by the wildcard argument. Valid dataset types are: Coverage —Only coverages. Feature —Coverage or geodatabase dataset, depending on the workspace. GeometricNetwork —Only geometric network datasets. Mosaic —Only mosaic datasets. Network —Only network datasets. ParcelFabric —Only parcel fabric datasets. Raster —Only raster datasets. RasterCatalog —Only raster catalog datasets. Schematic —Only schematic datasets. Terrain —Only terrain datasets. Tin —Only TIN datasets. Topology —Only topology datasets. All —All datasets in the workspace. This is the default value. (デフォルト値は All)	String

リターン

データ タイプ	説明
String	A list containing dataset names returned from the function, limited by the wildcard and feature type arguments.

コードのサンプル

ListDatasets example

List Feature Dataset names that start with C.

import arcpy

arcpy.env.workspace = "C:/Data"
# Print to the Interactive window all the feature datasets in the workspace
#   that start with the letter C. 
#
datasetList = arcpy.ListDatasets("C*", "Feature")

for dataset in datasetList:
    print dataset
