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())

#BLZ👀
It seems to be in the accumulation phase lately.
If the candle closes below the support, we can say Stop-Loss. Then there will be a downside opportunity 📉
How did we come up with this analysis?
We used the Support and Resistance detection of Coinlegs algorithm 👑
Check it out today.
#BLZ follows a descending channel pattern and seems to be gearing up for a bullish breakout. The next key target to watch after the breakout is the internal minor resistance at $0.1550 .
If #BLZ holds steady at $0.1110, we could be on the brink of a significant bullish rally, much like those explosive moves we've seen before. A breakout above the crucial resistance at $0.150 could pave the way for a run toward even higher resistance zones
-caution is essential. If momentum weakens at this critical demand zone, we might see a pullback to the lower demand area around $0.0800-
#BLZ is moving up in the bullish channel on Daily time frame, price has a good support on Green zone,we expect another pump from this area 🚀

On the coin there are signs of formation of ascending OF, liquidity removal from below, and reaction from the OB area, so let's try to open long, on removal of upper magnets
