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())

#Antimicrobials are vital in fighting infectious diseases across humans, animals, and plants.
However, their effectiveness is diminishing, leading to a growing and urgent crisis known as #AntimicrobialResistance.
Let’s promote the responsible use and work together to combat #AMR.
#Handwashing is a basic and effective tool against infections.
If we do not become sick, we would not need to use #antimicrobials.
Encourage your loved ones to practice frequent #handwashing with soap under running water.
Do your part to prevent #AntimicrobialResistance
#Antimicrobials are becoming less effective against common infections in animals & humans.
🚫 Do not self-medicate
✅ Visit a healthcare professional when sick
Everyone has a role to play to ensure #antimicrobials continue to work.

#AntimicrobialResistance is one of the top 10 health threats in the world.
Everyone everywhere, including users and non-users of #antimicrobials have a role to play to prevent #AMR.
#BeAntimicrobialAware
Every year, the National Antimicrobial Resistance Technical Working Group joins the global community to raise awareness of the dangers of misuse or overuse of #antimicrobials.
Fighting #AMR is a global endeavour that must be addressed through a #OneHealth approach as evident in this year's theme of #WAAW2023: ‘Preventing #AntimicrobialResistance together”

Misuse or overuse of #antibiotics💊 & other #antimicrobials can reduce its effectiveness in treating common infections in animals & humans.
From 18th-24th November, we are joining the global health community to mark the annual #WorldAntimicrobialAwarenessWeek2022 .
#StayTuned
#AntimicrobialResistance is when medicines like #antimalarials, tetracycline, septrin, and amoxicillin no longer treat diseases they cured previously.
Everyone everywhere, including users and non-users of #antimicrobials has a role to play to prevent #AMR.
