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

- отмена задач

New report cites evidence of alleged military assistance to RSF from #Ethiopian base, raising regional security concerns
A new report by the #Yale School of Public Health’s Humanitarian Research Lab (#HRL) says it has found “high confidence” evidence of activity consistent with military assistance by Ethiopia to Sudan’s Rapid Support Forces (#RSF), raising concerns about escalating regional insecurity.
The report, published on 8 April, is based on satellite imagery and open-source data collected between late December 2025 and late March 2026.
It concludes that such activity is taking place at an Ethiopian National Defense Force (#ENDF) base in #Asosa town, in Ethiopia’s #Benishangul-Gumuz region.
HRL says its assessment is based on five key indicators observed at the Asosa base and not found at 14 other ENDF installations reviewed for comparison.
One of the central findings is the repeated presence of non-military commercial car carriers........

A legal group submitted to the #UN the most thorough legal analysis of Israel's actions concluding it is committing genocide against Palestinians in Gaza.
This is probably the most complete report to date that demonstrates how #Israel's attacks on #Palestinians in #Gaza meet the legal definition of #genocide.
It's a 100-page report, by legal experts at #Boston University School of Law, #Cornell Law School, #Yale Law School, and others.
The report's conclusion:
"Israel has committed the #genocidal acts of #killing, causing serious harm to, and inflicting conditions of life calculated to bring about the physical #destruction of #Palestinians in #Gaza, a protected group that forms a substantial part of the Palestinian people.
These #genocidal acts have been motivated by the requisite genocidal intent, as evidenced in this report by the statements of #Israeli leaders, the character of the State and its forces’ conduct against and relating to Palestinians in Gaza, and the direct nexus between them."
