请用python写一个多人聊天室服务器

好的，这是一个简单的多人聊天室服务器的例子：

import threading
import socket

class ChatServer:
    def __init__(self, host='127.0.0.1', port=5555):
        self.host = host
        self.port = port
        self.clients = []
        self.server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.server.bind((self.host, self.port))
        self.server.listen()

    def broadcast(self, message):
        for client in self.clients:
            client.send(message)

    def handle(self, client):
        while True:
            try:
                message = client.recv(1024).decode('utf-8')
                if message == '!quit':
                    client.close()
                    self.clients.remove(client)
                    client.join()
                    break
                self.broadcast(message)
            except:
                client.close()
                self.clients.remove(client)
                client.join()
                break

    def receive(self):
        while True:
            client, address = self.server.accept()
            client.send('Welcome to the chat room!'.encode('utf-8'))
            self.clients.append(client)
            client.start_new_thread(self.handle, (client,))

    def start(self):
        print('Server listening on {}:{}'.format(self.host, self.port))
        self.receive()

if __name__ == '__main__':
    ChatServer().start()

这是服务器端的代码。客户端可以使用类似的方式连接到服务器并发送和接收消息。

希望这对你有帮助。
