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

🔥🔥#Ethereum's Shanghai upgrade was completed 12 hours ago, let's review some stats:
➡️ Total $ETH staking is dropped from the peak of 18.163M to 17.476M ($34B)
➡️ Total withdrawn amount is about 124K $ETH (while the 24-hour deposit is 26.5K $ETH, so the net deposit is -97K $ETH ~ $192M)
➡️ Top withdrawer is LDO with 70,809 $ETH. But LDO won't allow users to withdraw until May, so most of the withdrawn $ETH is not liquidated.
➡️ $ETH price increases by 6% to $1,982, but with that price, 70% of stakers are still in loss (in USD terms)

Kraken initiates emails to clients for bankrupt FTX withdrawals, with payments under $50,000 expected within 60 days. BitGo might follow soon.
