Q on asyncio

[snippsat]

I get a warning msg from pycharm stating "Coroutine 'create_task' is not awaited".

Never run Asynchronous/Concurrency in editors as they can block.

Thanks! It's not actually an error. It just highlights that line as a warning.
So, there's no need to "create a task" as shown in my test code?

Code from menator01 will not run in the background,it will run the get_temp coroutine in the foreground,and nothing else will happen concurrently.
For coroutine to run in the background while performing other tasks,as you use need asyncio.create_task().
To eg add like stop/break after 3-minutes.

import asyncio
from datetime import datetime, timedelta

async def temperatures(t, stop_event):
    while not stop_event.is_set():
        now = datetime.now()
        print(f'Displaying every 5 secs. {now:%S}')
        await asyncio.sleep(t)
    print("Stopping temperatures after 3 minutes")

async def main():
    stop_event = asyncio.Event()
    temperature_task = asyncio.create_task(temperatures(5, stop_event))
    start_time = datetime.now()
    while not stop_event.is_set():
        print('Clocking every second')
        await asyncio.sleep(1)
        if datetime.now() >= start_time + timedelta(minutes=3):
            stop_event.set()
    await temperature_task

def run():
    try:
        asyncio.run(main())
    except KeyboardInterrupt as err:
        print(f'kb interrupted {err}')

if __name__ == "__main__":
    run()
