tkinter

[Informatico de Neurodesarrollo]

This code work fine, every 5 second test the connection to this machine 
(10.44.0.15) on my network.

#!/usr/bin/env python
# -*- coding: utf-8 -*-
#
#  DetectConn_1_0.py
#
#First: Testing connection
#

import socket, time

def isInternet():
     testConn = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
     output = testConn.connect_ex(('10.44.0.15', 80))
     if output == 0:
         return True
     else:
         return False
     testConn.close()

while True:
     if isInternet():
         print("Hay conexión")
     else:
         print("No hay conexión")

     time.sleep(5)


What's next?, I am all eyes
