構文

ListRasters ({wild_card}, {raster_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
raster_type	The raster type to limit the results returned by the wild card argument. Valid raster types are: BMP —Bitmap graphic raster dataset format.

コードのサンプル

ListRasters example

List ESRI GRID raster names in workspace.

import arcpy
from arcpy import env

# Set the current workspace
# 
env.workspace = "C:/Data/DEMS"

# Get a list of ESRI GRIDs from the workspace and print
#
rasterList = arcpy.ListRasters("*", "GRID")
for raster in rasterList:
    print raster
