Checking if a website is up via Python

Question

By using python, how can I check if a website is up? From what I read, I need to check the "HTTP HEAD" and see status code "200 OK", but how to do so ?

Hi this class can do speed and up test for your web page with this class:

 from urllib.request import urlopen
 from socket import socket
 import time


 def tcp_test(server_info):
     cpos = server_info.find(':')
     try:
         sock = socket()
         sock.connect((server_info[:cpos], int(server_info[cpos+1:])))
         sock.close
         return True
     except Exception as e:
         return False


 def http_test(server_info):
     try:
         # TODO : we can use this data after to find sub urls up or down    results
         startTime = time.time()
         data = urlopen(server_info).read()
         endTime = time.time()
         speed = endTime - startTime
         return {'status' : 'up', 'speed' : str(speed)}
     except Exception as e:
         return {'status' : 'down', 'speed' : str(-1)}


 def server_test(test_type, server_info):
     if test_type.lower() == 'tcp':
         return tcp_test(server_info)
     elif test_type.lower() == 'http':
         return http_test(server_info)
