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. #async
