client

#!/usr/bin/python3

import socket

#Create socket object
clientsocket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

#host = '192.168.1.104'
host = socket.gethostname()

port = 444

clientsocket.connect(('192.168.1.104', port)) #You can substitue the host with the server IP

#Receiving a maximum of 1024 bytes
message = clientsocket.recv(1024)

clientsocket.close()

print(message.decode('ascii'))

server

#!/usr/bin/python3

import socket

#Creating the socket object
serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

host = socket.gethostname() #Host is the server IP
port = 444 #Port to listen on 

#Binding to socket
serversocket.bind((host, port)) #Host will be replaced/substitued with IP, if changed and not running on host

#Starting TCP listener
serversocket.listen(3)

while True:
    #Starting the connection 
    clientsocket,address = serversocket.accept()

    print("received connection from " % str(address))
    
    #Message sent to client after successful connection
    message = 'hello! Thank you for connecting to the server' + "\r\n"
    
    clientsocket.send(message)

    clientsocket.close()
