I've an issue with proper termination of an async python code running in a jupyter notebook cell. I would like to use the stop button on a jupyter notebook cell to exit cleanly the code running in the cell. I thought at first I could use the asyncio.CancelledError exception as it seems jupyter cell run as async, but I've a weird behavior with the code below : import asyncio try: await asyncio.sleep(3) except asyncio.CancelledError as e: print("Caught exception") print(e) except Exception as e: print(e) In this example if I press the stop button on the cell before the sleep is done, the asyncio.CancelledError is caught but only after the sleep is done... Is this expected behavior ? Is there a fix or another signal I could listen to in order to detect when the user request to stop the cell ? Continue reading...
