Asyncio Development Tutorials, Guides & Insights

In this tutorial, we'll delve into advanced generators and coroutines in Python. Generators and coroutines are powerful features that enable you to handle large datasets, write asynchronous code, and implement complex pipelines elegantly.

Generators are a type of iterable that yields items lazily, making them memory-efficient. Here, we'll explore advanced concepts like generator chaining, delegation, and usage in practical scenarios.

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()
