批量修改字段名

【解决办法】：
参考代码如下：

import arcpy    
arcpy.env.workspace = r''D:\Testing\New File Geodatabase (3).gdb''
featureclasses = arcpy.ListFeatureClasses()

for fc in featureclasses:
...     flds = arcpy.ListFields(fc, field_type=Short)  
...     for fld in flds:
...         if fld.name.startswith(Name):
...             
...             arcpy.AlterField_management(fc,fld.name,fld.name[0:4])
