I'm new to Python, so I'm not fully aware of all it can do. But this
simple ping test should work. It basicaly trys to ping the computer's
gateway.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
import os, sre, socket, string
def OnOffLine():
    # Gets your computers name and IP Address
    local_host_name = socket.gethostname()
    local_host_ip = socket.gethostbyname(local_host_name)
    # Splits your IP and atempts to guess your gateways IP
    remote_host = string.split(local_host_ip,".")
    remote_host = remote_host[:-1]
    remote_host_ip = ''
    for item in remote_host:
        remote_host_ip = remote_host_ip+item+'.'
    remote_host_ip = remote_host_ip+"1"
    # Pings your gateway
    ping = os.popen("ping "+remote_host_ip)
    data = ping.read()
    ping.close()
    # Searches for the number of times your hosts IP occurs and guesses
if your online or not
    ping_count = sre.findall(remote_host_ip,data)
    if len(ping_count) > 2:
        return "Online"
    else:
        return "Offline"
print OnOffLine()
