def get_ip_address(ifname): 
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) 
    return socket.inet_ntoa(fcntl.ioctl( 
        s.fileno(), 
        0x8915,  # SIOCGIFADDR 
        struct.pack('256s', ifname[:15]) 
    )[20:24]) 
 
print "eth0 = "+ get_ip_address('eth0') 
print "lo = " + get_ip_address('lo')
 

如果返回沒有的網絡卡會出錯

Traceback (most recent call last):  File "getmac.py", line 17, in <module>    print "eth1 = "+ get_ip_address('eth1')   File "getmac.py", line 13, in get_ip_address    struct.pack('256s', ifname[:15]) IOError: [Errno 99] Cannot assign requested address

第二種方法：

利用命令：

ip=`ifconfig eth0 | grep "inet addr" | awk -F: '{print $2}' | awk '{print $1}'`
mac=`ifconfig | grep HWaddr | awk -F" " '{print $5}'`

import  os

tmptxt=" ifconfig eth0 | grep "inet addr" | awk -F: '{print $2}' | awk '{print $1}'"

IPTMP=os.popen(tmptxt).read()

IP=IPTMP.replace("\n","")
