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

📖Title : Lady Chatterley's Lover
✍️Author : D. H. Lawrence
⭐️Rating : 3.50/5 (Goodreads)
📆Published : Jan 01, 1928
————————————————
Summary:Lady Chatterley’s Lover by D.H. Lawrence tells the story of Constance (Lady Chatterley), a young woman trapped in a passionless marriage to Sir Clifford, a paralyzed war veteran more concerned with intellect than intimacy. Emotionally and physically unfulfilled, she begins an affair with Oliver Mellors, the gamekeeper on their estate. Their relationship blossoms into a deep, sensual, and emotional connection, breaking through rigid class divisions and societal expectations. Through this affair, Constance rediscovers her own desires and the power of human connection. The novel explores themes of love, class, sexuality, and personal freedom in a repressive, post-war English society.
