Prompt for user input using python asyncio.create_server instance

asyncio.create_server is used to create a TCP server using asyncio. However, user input is generally not captured directly within the context of a server created using asyncio.create_server. Instead, you would handle user interactions through client connections to the server.

Here's how you could capture user input and interact with clients using asyncio.create_server:

import asyncio async def handle_client(reader, writer): while True: try: data = await reader.read(100) message = data.decode() if message.strip().lower() == 'exit': writer.write("Goodbye!\n".encode()) await writer.drain() break response = f"Received: {message}" writer.write(response.encode()) await writer.drain() except asyncio.CancelledError: break writer.close() async def main(): server = await asyncio.start_server( handle_client, '127.0.0.1', 8888) async with server: await server.serve_forever() asyncio.run(main()) 

In this example:

1. The handle_client coroutine reads and responds to messages from clients. It listens for messages and, if the message is "exit", it sends a "Goodbye!" message and breaks out of the loop.

2. The main coroutine creates a TCP server using asyncio.start_server. It binds to 127.0.0.1 on port 8888. The server listens for client connections and invokes the handle_client coroutine for each connected client.

3. The asyncio.run(main()) call runs the main coroutine.

Remember that this example demonstrates a simple server-client interaction using asyncio. User input is typically captured and sent by clients connecting to the server, not directly from the create_server instance. If you want to interactively provide input to the server, you might need to use threading or multiprocessing in conjunction with asyncio.
