We’ll use the websockets library to handle communication between players.

import asyncio
import websockets
import json

game = TicTacToe()
players = []

async def handler(websocket, path):
    global players
    players.append(websocket)
    try:
        async for message in websocket:
            data = json.loads(message)
            if "move" in data:
                position = data["move"]
                response = game.make_move(position)
                for player in players:
                    await player.send(json.dumps({"board": game.board, "status": response}))
    except websockets.ConnectionClosed:
        players.remove(websocket)

start_server = websockets.serve(handler, "localhost", 8765)

asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()
