**Simple Chat Application using Python** ===================================== Here is a simple code for a chat application using Python: **Server Side (chat_server.py)** ```python import socket import threading HOST = '127.0.0.1' PORT = 9090 server = socket.socket(socket.AF_INET, socket.SOCK_STREAM) server.bind((HOST, PORT)) server.listen() clients = [] nicknames = [] def broadcast(message): for client in clients: client.send(message) def handle(client): while True: try: message = client.recv(1024) broadcast(message) except: index = clients.index(client) clients.remove(client) client.close() nickname = nicknames[index] broadcast(f'{nickname} left the chat!'.encode('ascii')) nicknames.remove(nickname) break def receive(): while True: client, address = server.accept() print(f"Connected with {str(address)}") client.send('NICK'.encode('ascii')) nickname = client.recv(1024).decode('ascii') nicknames.append(nickname) clients.append(client) print(f'Nickname of the client is {nickname}!') broadcast(f'{nickname} joined the chat!'.encode('ascii')) client.send('Connected to the server!'.encode('ascii')) thread = threading.Thread(target=handle, args=(client,)) thread.start() print("Server Started!") receive() ``` **Client Side (chat_client.py)** ```python import socket import threading HOST = '127.0.0.1' PORT = 9090 client = socket.socket(socket.AF_INET, socket.SOCK_STREAM) client.connect((HOST, PORT)) def receive(): while True: try: message = client.recv(1024).decode('ascii') if message == 'NICK': client.send(nickname.encode('ascii')) else: print(message) except: print("An error occurred!") client.close() break def write(): while True: message = f'{nickname}: {input("")}' client.send(message.encode('ascii')) nickname = input("Choose a nickname: ") receive_thread = threading.Thread(target=receive) receive_thread.start() write_thread = threading.Thread(target=write) write_thread.start() ``` **How to use:** 1. Run the `chat_server.py` script in a separate terminal or command prompt. 2. Run multiple instances of the `chat_client.py` script in separate terminals or command prompts. 3. Each client will be prompted to enter a nickname. 4. Clients can send messages to each other by typing and pressing enter. Note: This is a very basic implementation and you may want to add more features such as error handling, encryption, and more.
