ArcPy 批量给shp字段赋值

工作中需要做大量图层的拼接，为了在拼接完成后还能知道原始数据文件是什么，所以写了个Python脚本对每个图层的SOURCE字段进行赋值。

附上Python代码：

# -*- coding: utf-8 -*-
# nightroad
import sys
import arcpy

path = "C:/Users/nightroad/Desktop/SHP"
arcpy.env.workspace = path
ff = arcpy.ListFeatureClasses()
for fc in ff:
    print(fc.replace(".shp", ""))
    arcpy.CalculateField_management(fc,"SOURCE",'"'+fc.replace(".shp", "")+'"',"PYTHON_9.3")
    print('Success:'+fc)
