在Arcpy中获取了一个.shp上的几何元素，如何获取该几何元素的attributes

import arcpy



g = arcpy.Geometry()

geometryList = arcpy.CopyFeatures_management("E:/myMapData/New_Shapefile.shp",g)



length = 0

for geometry in geometryList:

    length += geometry.length  

    print(s)

print "Total length: %f" % length

#这是获取几何元素的方法

import arcpy

srcRows = arcpy.SearchCursor("E:/myMapData/New_Shapefile.shp")

for row in srcRows:

    s=row.getValue("Id")

    print(s)

#获取Id
