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

🇺🇸🇺🇦🇷🇺Former Virginia State Senator, Col. Richard H. Black (ret.) on murder ofDugina
"[...]Just this week, Daria Dugina, the daughter of an activist, a pro-Russian activist, was murdered in Moscow, apparently by a Ukrainian assassin who killed her using a bomb that exploded under her car, ripping her body to pieces and burning her to death. Since the United States has admitted being involved in targeting 13 Russian Generals for assassination in Ukraine, it is possible that the CIA provided the targeting information to go after this young woman.
Apparently, they were actually targeting her father. He’s an established pro-Russian pro-war journalist. And they wanted to show that they have the ability to go right into Moscow and to carry out a mafia style hit. So, they did it. I would not be surprised if the CIA provided the targeting information to go after her. It was just a last-minute switch of automobiles that caused the daughter to die instead of the father."

🇺🇸🇷🇺🇺🇦Former US Marine Corps intelligence officer and UN inspector Scott Ritter:The murder of Daria Dugina was an act of terrorism
'Today, I’m a 61-year-old writer living in the suburbs of Albany, New York. [...] And yet, due to recent circumstances, I once again find myself inspecting my vehicle before getting inside, keeping a watchful eye out for strange vehicles driving down my street and conducting counter-surveillance maneuvers while driving.
Why the paranoia? Simply put, my name has been added to a Ukrainian “kill list.” Think I’m getting too wound up? Ask the family of Daria Dugina, the 29-year-old daughter of the Russian philosopher Alexander Dugin. Both she and her father were on the same list. Both were targeted for death by an assassin dispatched by the Ukrainian security services. [...]
The existence of the Myrotvorets “death list” is an instrument of terror and should be taken down at the insistence of the U.S. Government.'

🇺🇸🇺🇦🇷🇺“They Killed Her Because Of Her Ideas”: Russian Political Scientist Valery Korovin on Daria Dugina assissination
"Her death was a serious loss for the global intellectual conservative environment of the opponents of globalization and the very idea of the modern world.
Also, her tragic death as a result of a terrorist act, caused serious damage to the activities of the entire intellectual group headed by the world’s leading philosopher, author of the modern Russian geopolitical school, Eurasianist and intellectual Alexander Dugin.
Serious funds from American taxpayers are spent on personally discrediting Dugin and his movement, one slanderous campaign follows another, the best political technologists are working to discredit Dugin and his ideas in the wake of the State Department and the CIA."
