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.

Hi there! 😃
We’ve been wondering how keen you are on walking 👟- maybe you have a job that keeps you on your feet, or walking happened to be your favourite pastime?
🐾 In Walken, the more you walk, the higher 📈 your step count is - the more in-game Gems 💎you’ll get!
Given that 1ksteps = 1 gem , how many Gems 💎 would you get per day (on average) today?
A quick reminder: the app is not available yet, and we’re doing our best to bring it live as soon as possible! Initial DEX offering (IDO) is coming late Feb, will do our best to start a beta before that. There will be both iOS and Android version, so no worries!
