my code

import subprocess

import re

def get_arguments():
parser = optparse.OptionParser()
parser.add_option(“-i”, “–interface”, help=”interface to change its mac addreesses”, dest=”interface”)
parser.add_option(“-m”, “–mac”, dest=”new_mac”, help=”new mac addreesses”)

if not options.interface:

elif not options.new_mac:
parser.error(“[-] please specify an mac, se –help for more info.”)
return options

def change_mac(interface, new_mac):
subprocess.call([“ifconfig”, interface, “down”])
subprocess.call([“ifconfig”, interface, “hw”, “ether”, new_mac])
subprocess.call([“ifconfig”, interface, “up”])

options=get_arguments()

#change_mac(options.interface, options.new_mac)

ifconfig_result = subprocess.check_output([“ifconfig”, options.interface])
print(ifconfig_result)
mac_address_search_result = re.search(r”\w\w:\w\w:\w\w:\w\w:\w\w:\w\w”,ifconfig_result)
print(mac_address_search_result.group(0))

I followed step by step, what is the issue?
