Python programming are used to create a chat application

In this program is help to chat with client to server and server to client to send sms.
there are 2 python programs are run in two different CMD.

Step1: server.py  to save these program

import socket
import time


def Main():
    host = "172.16.1.81"
    port = 8080
               
    mySocket = socket.socket()
    mySocket.bind((host,port))
               
    mySocket.listen(1)
    print("socket is Listeining")
    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)
        print ("Received from User: " + str(data))

        data = input("Enter your Message :")
        conn.send(data.encode())
                                               
    conn.close()
               
               
if __name__ == '__main__':
                Main()

open CMD and run
python server.py


step2: clent_server.py 

import socket

def Main():
host = '172.16.1.81'
port = 8080

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


message = input("Enter your message: ")

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

print ('Received from server: ' + data)

data = input("Enter uour mesage: ")

mySocket.close()

if __name__ == '__main__':
Main()

open another CMD run this program 

python client_server.py
