You can use urllib2 and socket module for the task.
import socket
from urllib2 import urlopen, URLError, HTTPError
socket.setdefaulttimeout( 23 ) # timeout in seconds
url="http://google.com/"
try :
response = urlopen( url )
except HTTPError, e:
print 'The server couldn\'t fulfill the request. Reason:', str(e.code)
except URLError, e:
print 'We failed to reach a server. Reason:', str(e.reason)
else :
html = response.read()
print 'got response!'
# do something, turn the light on/off or whatever
