How is asynchronous execution of operations implemented when interacting with user input?

In Python, asynchronous execution of user input operations is usually implemented using the asyncio module. Instead of a blocking call to input(), you can use asynchronous functions that do not block the main execution thread and allow other tasks to be processed in parallel.

An example of using asynchronous input with asyncio and the aiofiles library or third-party solutions (since the standard input() does not support asynchrony directly):

import asyncio

async def async_input(prompt: str = '') -> str:
    print(prompt, end='', flush=True)
    loop = asyncio.get_event_loop()
    return await loop.run_in_executor(None, input)

async def main():
    name = await async_input('Enter your name: ')
    print(f'Hello, {name}!')

asyncio.run(main())

Here, run_in_executor runs the blocking input() function in a separate thread, not blocking the main event loop. Thus, other asynchronous operations can be performed in parallel while waiting for user input.
