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())

Audi has officially unveiled the new generation A6!
Now, this index belongs to electric vehicles — a liftback and an estate version.
🚘 The exterior of the new models is almost entirely copied from the namesake concepts, while the interior is inspired by the Q6 e-tron crossover.
🚢 The base version will be the rear-wheel drive A6 e-tron performance with a single motor producing 367 hp. For the S6, there will be two motors delivering 550 hp and accelerating from 0 to 100 km/h in just 3.9 seconds, with a top speed of 240 km/h.
🔋 In both cases, a 100 kWh battery is provided, allowing the single-motor versions to travel up to 756 km, while the all-wheel drive versions can reach up to 675 km.
ℹ️ Pre-orders will start in September, with prices starting at €75,600 for the standard version and €99,500 for the S6.
