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.

⚖️🗳️ALABAMA GOP RACES TO REDRAW HOUSE MAPS BEFORE 2026
🔹 Special session passes bills for NEW House primaries if courts approve GOP maps 📋⚡
🔹 Target: Flip Democratic Rep. Shomari Figures' AL-02 seat back to Republican 🔄
🔹 Would pack Black voters into fewer districts despite 27% of state population 👥
🔹 Gov. Kay Ivey: "Alabama stands ready to quickly act" on favorable rulings 🏛️
Democrats call it a "power grab echoing Jim Crow" — but GOP says Alabama's Republican tilt should match its maps! 11th Circuit decision could flip House control! ⚖️🔥🇺🇸

🌠 On November 30, 1954, Ann Hodges of Sylacauga, Alabama, became the first documented person in modern history to be struck by a meteorite. The rock crashed through her roof 🏠, bounced off a radio 📻, and struck her hip, leaving a large bruise 💢. She became an overnight sensation, but the event took a heavy toll on her life 😔.

U.S. States Embrace Bitcoin Reserves
