from arcpy import env

# Set the workspace for ListFeatureClasses

env.workspace = r"C:\Users\mohamed.abdelhamid\Desktop\Python\test\rename_test.gdb"

fcs = arcpy.ListFeatureClasses()

# Get the subdistric name from attribute

for itmes in fcs:

    field1  = "DIS_ARB_NA"

    field2 = "SDIS_ARB_N"

    cursor = arcpy.SearchCursor(itmes)

        disname = row.getValue(field1)

        subname = row.getValue(field2)

        arcpy.Rename_management(in_data=itmes,out_data=disname + "_" + subname,data_type="FeatureClass")

Hello Mohammed,

Based on your title I assume you want to rename the feature classes in a workspace based on an attribute from the feature class? Can you try this:

import arcpy

from arcpy import env

env.workspace = r"C:\Users\mohamed.abdelhamid\Desktop\Python\test\rename_test.gdb"

fields = ["DIS_ARB_NA","SDIS_ARB_N"]

for fc in arcpy.ListFeatureClasses():

    with arcpy.da.SearchCursor(fc,fields) as cursor:

        disname = row[0]

        subname = row[1]

        arcpy.Rename_management(fc, str(disname + "_" + subname), "FeatureClass")
