	async def response(websocket, path):
	message = await websocket.recv()
	print(f"We got the message from the client: {message}")
	await websocket.send("I can confirm I got your message!")
	start_server = websockets.serve(response, 'localhost', 1234)
	asyncio.get_event_loop().run_until_complete(start_server)
	asyncio.get_event_loop().run_forever()

client side=>

import asyncio
	import websockets
	async def message():
	async with websockets.connect("ws://localhost:1234") as socket:
	msg = input("What do you want to send: ")

Writing a PEP8 Standart of Python Code

Hi, 

I use flake8 in my code you should install :

pip install flake8

After that you can use like:

 flake8 example.py

In the Visual Studio Code you can use cornflakes-linter

If you want to ignore some error create a 

.flake8

file and write:

[flake8]

ignore=E501 

Example ss for flake8 and cornflakes-linter in VS Code

This is the website of flake8 you can check for more details.
