arcmap窗口中arcpy的使用

fields=[]
with arcpy.da.SearchCursor("海南省_市界","NAME") as cursor2:
for row in cursor2:
if row[0] not in fields:
fields.append(row[0])
for sel in fields:
arcpy.Select_analysis("海南省_市界","e:\\"+sel+".shp","\"Name\"= '"+sel+"'")

 

>>> with arcpy.da.SearchCursor("市界_CopyFeatures","cityname") as cursor2:
... for row in cursor2:
... arcpy.SelectLayerByAttribute_management("市界_CopyFeatures","NEW_SELECTION","cityname='"+row[0]+"'")
... arcpy.CopyFeatures_management("市界_CopyFeatures","e:\\test2\\"+row[0])
... arcpy.Buffer_analysis("e:\\test2\\"+row[0]+".shp","e:\\test2\\"+row[0]+"_buffer","100 Meters")

 

 

直接敲代码，回车时空一行时再回车即会执行。

 

1.在ArcMap中打开c:\ArcpyBook\Ch2\Crime_Ch2.mxd文件。
2.打开Python窗体。
3.导入arcpy.mapping模块：

import arcpy.mapping as mapping

4.获取当前地图文档的引用（Crime_Ch2.mxd）：

mxd = mapping.MapDocument("CURRENT")

5.调用arcpy.mapping.ListLayers函数：

print mapping.ListLayers(mxd)
