Web socket in python

#1) Installation
#Go to your cmd and type pip install websockets

#2) Utilisation 
#Here’s how a client sends and receives messages:

import asyncio
import websockets

async def hello():
    async with websockets.connect("ws://localhost:8765") as websocket:
        await websocket.send("Hello world!")
        await websocket.recv()

asyncio.run(hello())

#And here’s an echo server:

import asyncio
import websockets

async def echo(websocket):
    async for message in websocket:
        await websocket.send(message)

async def main():
    async with websockets.serve(echo, "localhost", 8765):
        await asyncio.Future()  # run forever

asyncio.run(main())
