Python Sockets: how to connect between two computers on the same wifi
<p>I have a setup of two laptops next to each other and would like to send messages between them, I found code that works when both the client and the server is on the same computer, but it won't work when they are separated.</p>

<pre><code>#SERVER
import socket

def Main():
    host = "localhost"
    port = 5000

    mySocket = socket.socket()
    mySocket.bind((host,port))

    mySocket.listen(1)
    conn, addr = mySocket.accept()
    print ("Connection from: " + str(addr))
    while True:
            data = conn.recv(1024).decode()
            if not data:
                    break
            print ("from connected  user: " + str(data))

            data = str(data).upper()
            print ("sending: " + str(data))
            conn.send(data.encode())

    conn.close()

if __name__ == '__main__':
    Main()


#CLIENT
import socket

def Main():
        host = '0.0.0.0'#127.0.0.1
        port = 5000

        mySocket = socket.socket()
        mySocket.connect((host,port))

        message = input(" -&gt; ")

        while message != 'q':
                mySocket.send(message.encode())
                data = mySocket.recv(1024).decode()

                print ('Received from server: ' + data)

                message = input(" -&gt; ")

        mySocket.close()

if __name__ == '__main__':
    Main()
</code></pre>

<p>I have tried many different addresses, including, 0.0.0.0, localhost, 192.168... &lt;- ip from ifconfig. What is the problem? and what should I look into for the best solution?</p>
