ArcPy进行要素编辑

fc = 'polygon.shp'
arcpy.CreateFeatureclass_management(out_path=outpath,out_name=fc,geometry_type='POLYGON')
cursor =arcpy.da.InsertCursor(fc,['SHAPE@'])
array = arcpy.Array()
point = arcpy.Point()
for line in fileinput.input(infile):
    point.ID,point.X,point.Y = line.split(' ')
    array.append(point)
polygon = arcpy.Polygon(array)
cursor.insertRow([polygon])
fileinput.close()
del cursor
