Python ARP扫描仪动态打印和更新输出

Question

嗨，我是python的新手，我只是用python2编写了此ARP扫描器，该扫描器扫描了网络中的所有设备并返回IP和MAC地址。我在Linux Terminal中运行代码。它工作正常，但我不知道如何在其上使用动态打印，因为我想每2秒更新一次扫描结果...

#!/usr/bin/env python

import scapy.all as scapy

def scan(ip):
    arp_request = scapy.ARP(pdst=ip)
    broadcast = scapy.Ether(dst = "ff:ff:ff:ff:ff:ff")
    arp_request_broadcast = broadcast/arp_request
    answered_list = scapy.srp(arp_request_broadcast, timeout = 1, verbose = False)[0]

    clients_list = []

    for element in answered_list:
        client_dict = {"ip": element[1].psrc, "mac": element[1].hwsrc}
        clients_list.append(client_dict)
    return clients_list

def print_result(results_list):
        print ("IP\t\t\tMAC\n"+"-"*60)
        for client in results_list:
            print(client["ip"] + "\t\t" + client["mac"])

scan_result = scan('192.168.1.0/24')
print_result(scan_result)

我尝试将while循环与子进程一起使用以在终端中运行“清除”命令，但结果不是很漂亮！
