Can you tell about your recent experience using WebSocket for data exchange?

In one of my recent projects in Python, I used the websockets library to implement bidirectional data exchange between server and client in real-time. This allowed updating the user interface without constantly polling the server.

Example of a simple Python server using websockets:

import asyncio
import websockets

async def echo(websocket, path):
    async for message in websocket:
        await websocket.send(f"Echo: {message}")

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

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

This approach is suitable for chats, gaming applications, and any systems where low latency message exchange is important.
