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())

#Ethiopia: Report warns of arbitrary detentions, growing restrictions on media in Addis Ababa
-------
A new report by Human Rights First has raised concerns over alleged arbitrary detentions and increasing restrictions on media in #Addis_Ababa, particularly during periods of major international events.
The report, titled “Situational Analysis of Human Rights in Addis Ababa,” states that security forces carried out “pre-emptive detentions” across several parts of the capital without due process.
According to the findings, detentions were recorded in sub-cities including #Yeka, #Bole, and #Akaki_Kality, where individuals were held for more than a week without being charged or appearing before court.
In addition, the report highlighted what it described as a growing pattern of restrictive actions against media between 2025 and early 2026.

News: Report tracks #UAE-linked cargo flights to #Ethiopian military base amid regional power struggle
A cargo aircraft previously linked to the supply of weapons to armed groups in #Sudan has conducted multiple flights to Ethiopia in recent weeks, according to an exclusive investigation by the UK-based outlet Middle East Eye (MEE), raising questions about Ethiopia’s role in intensifying regional rivalries tied to the war in Sudan.
MEE reported that an Antonov An-124 cargo plane operated by UAE-based Maximus Air, and allegedly linked to Emirati military logistics, made repeated flights between #Abu_Dhabi and #Harar_Meda airbase, the main base of the Ethiopian Air Force.
Flight-tracking data reviewed by the outlet shows at least four trips to Harar Meda between 3 and 17 January, including one flight that later continued to Addis Abeba’s #Bole International Airport before departing for #Europe and #Asia.
While the purpose of the flights remains unclear...
