Функция asyncio.wait() это еще один способ вызвать множество асинхронных задач. Она работает в нескольких режимах. 1. Самый простой - ждем завершения всех задач async def main(): tasks = [asyncio.create_task(do_it(i)) for i in range(10)] done, pending = await asyncio.wait( tasks, return_when=asyncio.ALL_COMPLETED ) for task in done: try: print(task.result()) except Exception as e: print(e) Очень похоже на gather, но работает не так. ▫️возвращает не результаты, а два сета с объектами Task у которых можно забрать результат через task.result() если они в списке done ▫️не гарантирует порядок результатов так как оба объекта это set ▫️не выбрасывает исключение когда оно появляется, а сохраняет его в Task. Исключение появится когда попробуете забрать резултьтат. 2. Ждем завершения первой задачи, даже если там ошибка. async def main(): tasks = [asyncio.create_task(do_it(i)) for i in range(3)] done, pending = await asyncio.wait( tasks, return_when=asyncio.FIRST_COMPLETED ) # в done может быть несколько задач! for task in done: try: print(task.result()) except Exception as e: print(f"Fail: {e}") # Оставшиеся задачи в pending, как правило, нужно отменить, иначе они будут продолжать работать for task in pending: task.cancel() В сете done будут таски которые успели завершится, причем как успешно так и нет. 3. До первой ошибки. Тоже самое, но с аргументом FIRST_EXCEPTION done, pending = await asyncio.wait( tasks, return_when=asyncio.FIRST_EXCEPTION ) Функция завершается как только первая задача упадет с ошибкой. Учтите, что в любом случае done вы можете обранужить несколько задач, как с ошибками так и успешные. ↗️ Полный листинг примеров здесь #async

Our Wordle of the day – did you manage to get yours right today? Don’t forget to clear your table after eating at our hawker centres, coffeeshops and food courts. P.S. You don’t have to clean your table, as cleaners will be cleaning and sanitising tables. #ClearYourTable#ReturnYourTray#BinUsedTissues

As we begin dining out again, remember to practise good hygiene, to protect ourselves, other diners, and our cleaners – many of whom are seniors. When you’re done eating, remember to #ClearYourTable, #ReturnYourTray and #BinUsedTissues. Leaving litter on tables at our public dining places is an offence. NEA is taking an advisory approach in the lead-up to 1 Sep 2021, after which enforcement action will be taken against patrons who fail to heed our officers’ advice. www.nea.gov.sg/media/news/advisories/index/clear-table-as-dine-in-resumes

As dine-in gradually resumes from today, let’s do our part in keeping our favourite public dining spaces and our cleaners safe by remembering to #ReturnYourTray, #ClearYourTable and #BinUsedTissues. If we simply get up and walk away, the dirty crockery and food remnants can attract unwanted pests. Our used tissues also carry germs that pose potential health risks to cleaners and other diners.

Here’s what the same area at Queen’s St Hawker Centre looks like in 2016 and 2021. What a dramatic transformation we've seen lately! Better tray return infrastructure and a new cleaning workflow are initiatives we’ve adopted to ensure cleaner and safer public dining places. Diners and cleaners at #OurHawkerCentres have played a great part in making this system work. So next time you’re dining at #OurHawkerCentres, be part of that change and #ClearYourTable, #ReturnYourTray and #BinUsedTissues to keep our public dining places clean and safe for everyone.
