使用ArcPy將所有文件特徵數據（shapefile）從文件夾添加到MXD中

Question

我想問一些關於使用ArcPy處理ArcGIS地圖文檔（MXD）中的特徵數據的腳本。

我有一個在shapefile（shp）窗體中具有一些功能數據的文件夾。

• d：\ TES \ 2240.shp
• d：\ TES \ 2250.shp
• d：\ TES \ 22460.shp
• 等

我想創建一個可將上述數據添加到MXD的ArcPy腳本。

import arcpy 
mxd = arcpy.mapping.MapDocument(r"D:\tes\Operation.mxd") 
df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0] 
targetGroupLayer = arcpy.mapping.ListLayers(mxd, "Actual", df)[0] 
addLayer = arcpy.mapping.Layer(r"D:\data\2440.shp") 
arcpy.mapping.AddLayerToGroup(df, targetGroupLayer, addLayer, "TOP") 
addLayer = arcpy.mapping.Layer(r"D:\data\2450.shp") 
arcpy.mapping.AddLayerToGroup(df, targetGroupLayer, addLayer, "TOP") 
addLayer = arcpy.mapping.Layer(r"D:\data\2460.shp") 
arcpy.mapping.AddLayerToGroup(df, targetGroupLayer, addLayer, "TOP") 
mxd.saveACopy(r"D:\tes\Operation_2.mxd") 
del mxd, addLayer 

我想改變腳本的路徑源數據上面，在這部分

addLayer = arcpy.mapping.Layer(r"D:\data\2440.shp") 

因此腳本可以在文件夾中添加所有SHP數據：我可以單獨使用這個腳本添加文件使用擴展名，而不是每個文件名硬編碼。有點像這樣：

addLayer = arcpy.mapping.Layer(r"D:\data\*.shp") 

什麼是正確的方法來做到這一點？

Create a list of all the shapefiles in the directory，然後遍歷它。

import arcpy 
mxd = arcpy.mapping.MapDocument(r"D:\tes\Operation.mxd") 
df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0] 

# set workspace to directory of interest 
arcpy.env.workspace = r"D:\data" 
# create list of all files ending in .shp 
list_shapefiles = arcpy.ListFiles("*.shp") 

targetGroupLayer = arcpy.mapping.ListLayers(mxd, "Actual", df)[0] 
# loop through list, adding each shapefile to group layer 
for shapefile in list_shapefiles: 
    addLayer = shapefile 
    arcpy.mapping.AddLayerToGroup(df, targetGroupLayer, addLayer, "TOP") 

mxd.saveACopy(r"D:\tes\Operation_2.mxd")
