Python Chat Application

It is a simple project and contains two python scripts server.py which handle client request and client.py send request and receive response from the server through socket communication.

Prerequisites

In order to run the python script, your system must have the following programs/packages installed and the contact number should be saved in your phone (You can use bulk contact number saving procedure of email). There is a way without saving the contact number but has the limitation to send the attachment.

• Python 3.8

Approach

• server.py needed to execute in terminal.
• client.py needed to execute from the client machine and enter the hostname or IP address.
• the server will establish connection between the server and the client through socket.
• now from the server or client text can be sent.

Server Code

# Program to accept client request
# Author @inforkgodara

import socket

s = socket.socket()
host = socket.gethostname()
print(' Server will start on host : ', host)
port = 8080
s.bind((host, port))
print()
print('Waiting for connection')
print()
s.listen(1)
conn, addr = s.accept()
print(addr, ' Has connected to the server')
print()
while 1:
    message = input(str('>> '))
    message = message.encode()
    conn.send(message)
    print('Sent')
    print()
    incoming_message = conn.recv(1024)
    incoming_message = incoming_message.decode()
    print(' Client : ', incoming_message)
    print()

Client Code

# Program to send request to the server
# Author @inforkgodara

import socket

s = socket.socket()
host = input(str('Enter hostname or host IP : '))
port = 8080
s.connect((host, port))
print('Connected to chat server')
while 1:
    incoming_message = s.recv(1024)
    incoming_message = incoming_message.decode()
    print(' Server : ', incoming_message)
    print()
    message = input(str('>> '))
    message = message.encode()
    s.send(message)
    print('Sent')
    print()
