ARCPY 10.0 令牌获取的 shape@length 怎么输出成数值

rows = arcpy.SearchCursor(fc,[[email]SHAPE@LENGTH[/email]])
for row in rows: print(row)
输出结果是
<geoprocessing row object object at 0x0FB0CED8>
<geoprocessing row object object at 0x0FB0CEC0>
<geoprocessing row object object at 0x0FB0CEA8>
<geoprocessing row object object at 0x0FB0CE90>
而不是数值有什么办法输出如1.23之类的数值
