[python] Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time

def check_web_server(host, port, path):
        h = httplib.HTTPConnection(host, port)
        h.request('GET',path)
        resp = h.getresponse()
        print 'HTTP Response:'
        print '   status =', resp.status
        print '   reason =', resp.reason
        print 'HTTP Headers:'
        for hdr in resp.getheaders():
                print '  %s: %s' % hdr

I called this function like this check_web_server('www.python.org',80,'/') but it gave me this error error: [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
