ArcMap中如何删除属性域

import arcpy
#Set workspace environment to geodatabase
arcpy.env.workspace = your_gdb

#Get list of feature classes in geodatabase
FCs = arcpy.ListFeatureClasses()

#Loop through feature classes in list
for FC in FCs:

   #List fields in feature class
   fields = arcpy.ListFields(FC)

      #Loop through fields
      for field in fields:

         #Check if field has domain
         if field.domain != '':

            #Print feature class, field, domain name
            print FC, field.name, field.domain
