Find MAC address of system in python

Simple we can find mac addresses by socket connection and netifaces library. first you have to download this library from given below link according to python version and OS .

https://pypi.python.org/pypi/netifaces#downloads

from socket import *
import netifaces as nif
def mac_for_ip(ip):
    'Returns a list of MACs for interfaces that have given IP, returns
None if not found'
    for i in nif.interfaces():
        addrs = nif.ifaddresses(i)
        try:
            if_mac = addrs[nif.AF_LINK][0]['addr']
            if_ip = addrs[nif.AF_INET][0]['addr']
        except IndexError, KeyError: #ignore ifaces that dont have MAC or IP
            if_mac = if_ip = None
        if if_ip == ip:
            return if_mac
    return None

print mac_for_ip(gethostbyname_ex(gethostname())[2][0])
