I've been looking over various internet postings and a lot of the code I've seen looks similar to this:

def mactobinar(mac):
    addr = ''
    temp = mac.replace(':', '')

    for i in range(0, len(temp), 2):
        addr = ''.join([addr, struct.pack('B', int(temp[i: i + 2], 16)))])

    return addr

Can someone explain how this code works?
