Отдельно разберём TaskGroup, который пришел на замену gather в Python 3.11.
Ключевые отличия
▫️create_task() возвращает объект asyncio.Task, у которого есть соответствюущие методы управления. То есть у нас больше контроля
▫️это контекстный менеджер, который гарантирует что все таски будут остановлены по выходу из контекста
▫️ошибка автоматически отменяет незавершенные задачи,
▫️except* передает нам ExceptionGroup, в котором каждую ошибку можно обработать отдельно
import asyncio
import random
async def do_it() -> str:
if random.random() < 0.1:
raise ValueError('Oops')
delay = random.uniform(0.5, 1.5)
await asyncio.sleep(delay)
return delay
async def main():
try:
async with asyncio.TaskGroup() as tg:
for _ in range(10):
tasks.append(tg.create_task(do_it()))
for t in tasks:
print(t.result())
except *ValueError as e:
for err in e.exceptions:
print(err)
asyncio.run(main())
Рекомендую изучить страницу Coroutines and Tasks из документации, где представлено больше интересных примеров и механизмов
- таймауты
- отмена задач
- создание задач из другого потока

*FRACTION OF SECONDS*
Woke up. I knew I was late. Coz that was my routine. And coz of a simple logic, why be excited to wake up early and go to a place you hate and do something that you hate!
I sighed when my mouth tasted coffee before colgate...Ahh! how I love normal days, It was a normal day. At least that's what I thought. Papa was there looking up from the newspaper at me with a sense of pity.
I sort of ignored that and walked out through the front door, but the next sight, a brand new beautiful ladybird and an even more beautiful rider, with short black hair waving in the wind, in a skirt that knew well not to cover her beautiful legs... Well I couldn't ignore that! Just a fraction of seconds and I had already captured her. Made her mine. Is this what they call...
Oops!! She looked at me. Damn it! She caught me staring at her! I looked away whistling. I looked again, did I see a smile?
I heard Mom shouting my name out aloud. I knew I had to rush. As I was rushing inside I heard a loud thud. I turned back and saw the beautiful ladybird lying on the road. It was only a fraction of second, yet my mind talked to me in infinite speed...Somethings...what did he say I don't remember anymore. I remember rushing back to the house.
One year I didn't talk to our new neighbour who was an year older than me.Days went by. Mom had started packing things up one evening I came back from school. Papa received his transfer letter.
Now whenever I see a cycle I think. What would've happened? Why hadn't I stopped my mind talking to me? Why hadn't I I rushed 'out'side than 'in'side? All in a fraction of second!

#short story
Former US National Security Advisor John Bolton:
“Although you could potentially remove the ayatollah, that would leave the IRGC in place, and the government in Iran is the IRGC, while the ayatollahs act as a religious cover or an ideological cover for them.
I think Trump is just hoping that this show of American power will intimidate the ayatollahs. If I were still his adviser, I would be happy to tell him that it won’t work.
They won’t be intimidated. But Trump really thinks minute by minute; he doesn’t think strategically.”
