Socket python + send back message to client

Question

I have a basic python socket, like:

server.py

import socket
ip = '192.168.2.231'
port = 2005
addr = (ip, port)
serv_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
serv_socket.bind(addr)
serv_socket.listen(2)
con, cliente = serv_socket.accept()
receive = con.recv(1024)
if receive == '0123456789':
 #print "Accepted ACK"
 HERE - how can i send a message to client.py back
serv_socket.close()

How can i respond to the client.py that the sent ACK is correct? On line 16(server.py) I perform an IF and print a message, I want send a message back to the client.py saying that the ACK is invalid / invalid

Answer 1

You'll just use the client socket to send a response.

con, cliente = serv_socket.accept()
receive = con.recv(1024)
if receive == '0123456789':
 con.send("ACK")
serv_socket.close()
