How to send data to websocket with octave sockets library

I'm trying to send data from octave to python but i cant receive data and there is no error.

octave code

pkg load sockets
test = "example";
s = socket();
server_info = struct("addr", "127.0.0.1", "port", 9897);
sendto(s, test,server_info);

python code

import asyncio
import websockets

async def hello(websocket, path):
    async for message in websocket:
        print(message)

start_server = websockets.serve(hello, "127.0.0.1", 9897)

asyncio.get_event_loop().run_until_complete(start_server)

asyncio.get_event_loop().run_forever()
