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

#Policy_Brief: Coercion Over Consent: #Ethiopia’s dangerous mandatory Digital ID experiment
In this policy brief, Mohamed A. argues that Ethiopia's mandatory Digital ID (#Fayda) is a "flawed and dangerous policy," not because identification itself is problematic, but because enforcement lacks legal safeguards. He emphasizes that centralizing sensitive data risks turning governance into a tool of "surveillance, control, and exclusion."
According to him, Ethiopia is "importing the concept as if it were a proven model." In Ethiopia's fragile institutional context, this amounts to "recklessness disguised as modernization," especially with foreign funding raising unresolved questions about "who controls the data."
The author urges authorities to "pause enforcement" until trust and oversight are established, arguing that without them, mandatory ID is "not progress—it is a poorly designed and dangerous policy."
