Sample Code

# server.py
import socket
import threading

def client_thread(conn, addr):
    # Send a welcome message
    conn.send("Connected to the server. Type messages and press enter to send.\n".encode())

    while True:
        # Receiving message from client
        message = conn.recv(1024).decode()
        print(f"Received message from {addr}: {message}")
        if not message:
            break

        # Broadcasting message to all connected clients
        for client_conn in clients:

                except:
                    pass  # Handle error

    # Closing connection
    conn.close()

# Starting server
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind(('localhost', 12345))
server.listen()

clients = []

while True:
    conn, addr = server.accept()
    print(f"Connected with {addr}")
    clients.append(conn)
    threading.Thread(target=client_thread, args=(conn, addr)).start()

# client.py
import socket

            print(message)
        except:
            print("You have been disconnected from the server.")
            sock.close()
            break

# Connecting to server
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(('localhost', 12345))

# Starting the thread for receiving messages
threading.Thread(target=receive_messages, args=(sock,)).start()

while True:
    message = input('')
    if message == 'quit':
        break
    sock.send(message.encode())
