Три способа выполнить множество задач с asyncio
Функция для примера:
async def do_it(n):
await asyncio.sleep(random.uniform(0.5, 1))
return n
1. Последовательный вызов
async def main():
for i in range(100):
result = await do_it(i)
Такой вызов имеет смысл только тогда, когда результат одной задачи требуется для вызова следующей.
Если они независимы, то это антипаттерн, так как аналогичен простому синхронному вызову по очереди.
2. Упорядоченный результат
async def main():
tasks = [do_it(i) for i in range(100)]
results = await asyncio.gather(*tasks)
Выполняет корутины конкурентно и возвращает результат в виде списка.
Полезен когда требуется получить результаты в том же порядке в котором задачи отправлены.
3. Результат по мере готовности
tasks = [asyncio.create_task(do_it(i)) for i in range(100)]
for cor in asyncio.as_completed(tasks):
result = await cor
Так же выполняет корутины конкурентно, но не гарантирует порядок. Результат возвращается по мере готовности, каждый отдельно.
Полезен когда нужно обработать любой ответ как можно скорее.

🔥🔥#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➡️ Total withdrawn amount is about 124K $ETH (while the 24-hour deposit is 26.5K $ETH, so the net deposit is -97K $ETH ~ $192M)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 But LDO won't allow users to withdraw until May, so most of the withdrawn $ETH is not liquidated.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)

FTX clients with claims under $50,000 total $1.2 billion, says creditor group representative Sunil Kavoury. Claims filing extended until January 20, with payments likely in February. Kraken initiates emails to clients for bankrupt FTX withdrawals, with payments under $50,000 expected within 60 days. BitGo might follow soon.
