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.

📰Nissan, Honda and Mitsubishi refused to collaborate into a single holding company
❌ The companies officially canceled the memorandum of merger signed in December 2024. Negotiations lasted several months, but the parties were unable to reach an agreement.
ℹ️ Honda had proposed creating a single holding company in which it would gain management control and appoint a CEO. Another option was to turn Nissan into its subsidiary. Both options Nissan found unacceptable. The companies will now continue to cooperate, but only in software and electric cars.
💰 The collaboration was supposed to help compete with Tesla and BYD. The potential holding company was valued at $50 billion.

🚘Mitsubishi Motors to opt out of Honda-Nissan holding company
📰Mitsubishi Motors has finalized its decision not to participate in the management integration plan proposed by Honda and Nissan, citing fears of being marginalized, sources revealed on January 24.
🚘 Instead, Mitsubishi plans to remain under Nissan, its largest shareholder, while seeking ways to collaborate with both automakers.
ℹ️ Honda and Nissan are considering establishing a holding company in August 2026, with plans to delist and operate under a single umbrella. However, Mitsubishi intends to stay outside the holding company framework and maintain its position as a Nissan subsidiary, with Nissan holding just under 30% of Mitsubishi’s shares.
