My version:
async def ainput(prompt: str = ''):
with ThreadPoolExecutor(1, 'ainput') as executor:
return (await asyncio.get_event_loop().run_in_executor(executor, input, prompt)).rstrip()
Cannot remember why, as years have passed since.
This snippet is being useful in Pyrogram, in which I indeed eventually switched to using input
and getpass
as functions to be run in the executor. The use of sys.stdin.readline
and the thread initializer definitely looks unnecessary.
