使用python取系统主机名和IP地址以及过滤网卡信息等，供大家学习参考。

Windows 主机名IP地址：

复制代码 代码如下:#!C:\\python26\\python.exe

# -*- coding:UTF-8 -*-import socket# 主机名name = socket.gethostname()print name# 主机名（带域的后缀）myfullname = socket.getfqdn(socket.gethostname())print myfullname# IP 地址ip_addr = socket.gethostbyname(name)print ip_addr# 主机名和IP地址（多网卡）socket.gethostbyname_ex(socket.gethostname())

Linux 主机名IP地址：

复制代码 代码如下:#!C:\\python26\\python.exe

# -*- coding:UTF-8 -*-import socketimport fcntlimport structdef get_ip_address(ifname):    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)    return socket.inet_ntoa(fcntl.ioctl(        s.fileno(),        0x8915,        struct.pack('256s', ifname[:15])    )[20:24])print "LoopBack Addr: " + get_ip_address('lo')print "My IP Address: " + get_ip_address('eth0')

 

 
Windows 用命令过滤网卡信息：

复制代码 代码如下:#!C:\\python26\\python.exe

# -*- coding:gbk -*-import os,sysimport socketdef GetInfo(adp):    ''' [AdapterName, MacAddr, IPAddr, NetMask, Gateway] '''    NAME_INFO=[];IP_INFO=[];MAC_INFO=[];MSK_INFO=[];GW_INFO=[]    dict_ip={};dict_mac={};dict_msk={};dict_gw={}    cmd = "ipconfig /all"    txt = os.popen(cmd).readlines()    for line in txt:        if 'Ethernet adapter' in line:            NAME_INFO.append(line.split('adapter')[1].split(':')[0].strip())        if 'Physical Address' in line:            MAC_INFO.append(line.split(':')[1].strip())        if 'IP Address' in line:            IP_INFO.append(line.split(':')[1].strip())        if 'Subnet Mask' in line:            MSK_INFO.append(line.split(':')[1].strip())        if 'Default Gateway' in line:            GW_INFO.append(line.split(':')[1].strip())                for i in range(0,len(NAME_INFO)):        dict_ip[NAME_INFO[i]] = IP_INFO[i]        dict_mac[NAME_INFO[i]] = MAC_INFO[i]        dict_msk[NAME_INFO[i]] = MSK_INFO[i]        dict_gw[NAME_INFO[i]] = GW_INFO[i]    if adp not in dict_ip.keys():        print 'Error: No adapter name "%s" in this computer!' % (adp)        print 'You can select in: %s' % (NAME_INFO)        sys.exit()    else:        return [adp,dict_mac[adp],dict_ip[adp],dict_msk[adp],dict_gw[adp]]    if __name__ == '__main__':    NetWork_Adapter = '本地连接'    HOST_INFO = GetInfo(NetWork_Adapter)    print 'Mac地址 ............................. ' + HOST_INFO[1]    print 'IP地址 .............................. ' + HOST_INFO[2]    print '子网掩码 ............................ ' + HOST_INFO[3]    print '网关地址 ............................ ' + HOST_INFO[4]
