#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())
