When running the echo server example from chapter 10 under Python 3.10 or newer a TypeError is raised:
TypeError: BaseEventLoop.create_server() got an unexpected keyword argument 'loop'
The solution is to simply remove the 'loop' argument from line 17.
coro = asyncio.start_server(handle_echo, '127.0.0.1', 8888, loop=loop) # original
coro = asyncio.start_server(handle_echo, '127.0.0.1', 8888) # solution
This can be done safely because the function asyncio.get_event_loop that is used internally by asyncio.start_server always returns the currently running loop from Python 3.6 onwards.
