利用第三方模块netifaces收集网卡信息

　　利用第三方模块netifaces对网卡信息的分析比较简单。

import netifaces

def get_interface_list():
    return netifaces.interfaces()


def get_addresses(interface):
    result = netifaces.ifaddresses(interface)
    address_dict = {}
    for k,v in result.items():
        if k == 17:
            mac_address = v[0]['addr']
            address_dict['mac_address'] = mac_address
        elif k == 2:
            ip_address = v[0]['addr']
            net_mask = v[0]['netmask']
            address_dict['ip_address'] = ip_address
            address_dict['netmask'] = net_mask
    return address_dict

if __name__ == "__main__":
    interface_list = get_interface_list()
    for interface in interface_list:
        address_dict = get_addresses(interface)
        print("Interface information for %s: \n" % interface)
        print("IP address: %s" % address_dict['ip_address'])
        print("Netmask: %s\n" % address_dict['netmask'])
