TCP Server in Python

A simple TCP server in Python.

import socket
import threading

IP = '127.0.0.1' # IP of the server
PORT = 6969 # Port of the server


def handle_client(client): # Handle client connections
    with client as s:
        data = s.recv(4096)
        print(repr(data))
        s.send(b'ACK') # 'ACK' stands for Acknowledgement


def main():
    with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s: # Do this while Socket it open
        s.bind((IP, PORT)) # Link the IP and PORT to the Socket
        s.listen(5) # Listen with a max of 5 connections allowed

        print(f'Listening on {IP}:{PORT}')

        while True:
            client, address = s.accept() # Accept any connection requests
            print(f'Connected {address[0]}:{address[1]}')
            client_handler = threading.Thread(target=handle_client, args=(client,)) # Add client to thread
            client_handler.start() # Start the thread


if __name__ == '__main__':
    main()
