Python3根据IP地址获取MAC地址，python3ip获取mac,这是一种笨方法，是根据系

这是一种笨方法，是根据系统内置命令去获取的。我只是抛砖引玉，希望有人给我分享更好的代码，比如通过ARP协议去获取MAC地址？

#!/usr/bin/env python3# -*- coding: utf-8 -*-import osimport platformimport reclass IP2MAC:    def __init__(self):        self.patt_mac = re.compile('([a-f0-9]{2}[-:]){5}[a-f0-9]{2}', re.I)    def getMac(self, ip):        sysstr = platform.system()        if sysstr == 'Windows':            macaddr = self.__forWin(ip)        elif sysstr == 'Linux':            macaddr = self.__forLinux(ip)        else:            macaddr = None        return macaddr or '00-00-00-00-00-00'    def __forWin(self, ip):        os.popen('ping -n 1 -w 500 {} > nul'.format(ip))        macaddr = os.popen('arp -a {}'.format(ip))        macaddr = self.patt_mac.search(macaddr.read())        if macaddr:            macaddr = macaddr.group()        else:            macaddr = None        return macaddr    def __forLinux(self, ip):        os.popen('ping -nq -c 1 -W 500 {} > /dev/null'.format(ip))        result = os.popen('arp -an {}'.format(ip))        result = self.patt_mac.search(result.read())        return result.group() if result else Noneif __name__ =='__main__':    g = IP2MAC()    print(g.getMac('192.168.112.80'), g.getMac('192.168.1.254'), sep='\\n')#该片段来自于http://byrx.net
