Question

我需要创建一个查询网络接口的Python脚本，并返回主机名，IP地址和mac地址。

import java.util.Scanner;
import java.util.Random;

public class Nim {

    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        Random rand = new Random();

        int playernum;
        int cpunum = rand.nextInt(3)+1;
        int gamenum = 21;
        boolean win = false;
        boolean turn = true;

        while((win = false) && (turn = true)){
            System.out.println("The number is 21. Enter a number from 1 - 3");
            playernum = input.nextInt();

            int remaining = gamenum - playernum;

            System.out.println("The number is now " + remaining);
            turn = false;

            if((turn = false) && (gamenum > 0)){
                System.out.println("Computer is thinking...");
                try {
                    Thread.sleep(3000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }


            }
        }


    }

}

这是我正在使用的程序的一个版本。这似乎抓住了我需要的所有数据，但我不能让它打印干净或正确！我正在寻找类似的东西：＆＃34; Nic：wlan0，ipaddr：10.0.0.1，mac：4651168584541＆＃34;

我是编程的新手，也是python的新手，所以请任何帮助表示赞赏！

@ camflan的回复 Getting MAC Address

How to get the physical interface IP address from an interface

import netifaces

x = netifaces.interfaces()


for i in x:
    if i != 'lo':
        print(i)
        print("mac:" + netifaces.ifaddresses(i)[netifaces.AF_LINK][0]['addr'] + "     ipaddr:" + netifaces.ifaddresses(i)[netifaces.AF_INET][0]['addr'])
        i += i
    else:
        continue

首先这有点棘手，但这种格式应该允许你从netifaces的结果中获取数据。

import netifaces

x = netifaces.interfaces()


for i in x:
    if i != 'lo':
    print('\nInterface: ' + i)
    mac = netifaces.ifaddresses(i)[netifaces.AF_LINK][0]['addr']
    print('Mac addr: ' + mac)

    try:
        ip = netifaces.ifaddresses(i)[netifaces.AF_INET][0]['addr']

        print('IP addr: {0} '.format(ip))
    except KeyError:
        print('NO IP')
        continue

输出如下：

Interface: eth0
Mac add: eo:ie:9:38:ri
No IP

Interface: wlan0
Mac addr: 34:po:iu:66
IP addr: 10.0.0.1
