我被教导如何通过两种方法更改 mac 地址，subprocess.call第一种方法成功，但第二种方法给我错误，我无法理解它，这是我的代码：
#! /usr/bin/python3.5
import subprocess
interface = input("Enter Interface of Your Choice: ")
mac_chg = input("Enter New Mac Address: ")
print("[+]Changing Mac ADDRESS of " + interface + " to " + mac_chg)
subprocess.call(["ifconfig", interface, "down"])
subprocess.call(["ifconfig", interface, "hw", "ether", mac_chg])
subprocess.call(["ifconfig", interface, "up"])
这是错误：
Traceback (most recent call last):
