利用Python编写获取所有网卡名称以及网卡信息的代码

本文主要是介绍利用Python编写获取所有网卡名称以及网卡信息的代码，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

import subprocess
import sys


def banner():
    banner = """
        ******************************************************************
        ******************************************************************
                  Interface Inforamtion Display by Jason Wong V1.0
        ******************************************************************
        ******************************************************************
    """
    print(banner)

def get_interface_info(interface):
     mac_address = subprocess.check_output("ifconfig " + interface + " | grep ether | awk -F ' ' '{print $2}'", shell=True).decode('utf-8')
     ip_address = subprocess.check_output("ifconfig " + interface + " | grep 'inet ' | awk '{print $2}'", shell=True).decode('utf-8')
     return mac_address, ip_address


def main():
    """
    Step 1: Get the interface list
    Step 2: Get the information for each interface
    """
    banner()
    try:
        interface_list = subprocess.check_output('ifconfig | grep flags | cut -d ":" -f 1', stderr=subprocess.STDOUT, shell=True).decode('utf-8').split("\n")[0:-1]
        for interface in interface_list:
            mac_address, ip_address = get_interface_info(interface)
            print("******Interface [ %s ] information as follows:\n" % interface)
            print("\t\tMAC address: %s" % mac_address)
            print("\t\tIP address: %s\n" % ip_address)
            print("="*100)
    except Exception as e:
        print(e)
        sys.exit()

if __name__ == '__main__':
    main()

　　运行效果示意图如下：
