Have you worked with WebSocket protocol in your projects?

Yes, I have experience working with the WebSocket protocol in Python projects. WebSocket allows establishing a persistent, two-way connection between the client and server, which is useful for real-time applications such as chats, gaming servers, or monitoring systems.

For working with WebSocket in Python, libraries like websockets or aiohttp are commonly used.

Here's an example of a simple WebSocket server using the websockets library:

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 server receives messages from the client and sends them back with the prefix "Echo:". I have used similar solutions for real-time data exchange in projects.
