Функция asyncio.wait() это еще один способ вызвать множество асинхронных задач. Она работает в нескольких режимах. 1. Самый простой - ждем завершения всех задач async def main(): tasks = [asyncio.create_task(do_it(i)) for i in range(10)] done, pending = await asyncio.wait( tasks, return_when=asyncio.ALL_COMPLETED ) for task in done: try: print(task.result()) except Exception as e: print(e) Очень похоже на gather, но работает не так. ▫️возвращает не результаты, а два сета с объектами Task у которых можно забрать результат через task.result() если они в списке done ▫️не гарантирует порядок результатов так как оба объекта это set ▫️не выбрасывает исключение когда оно появляется, а сохраняет его в Task. Исключение появится когда попробуете забрать резултьтат. 2. Ждем завершения первой задачи, даже если там ошибка. async def main(): tasks = [asyncio.create_task(do_it(i)) for i in range(3)] done, pending = await asyncio.wait( tasks, return_when=asyncio.FIRST_COMPLETED ) # в done может быть несколько задач! for task in done: try: print(task.result()) except Exception as e: print(f"Fail: {e}") # Оставшиеся задачи в pending, как правило, нужно отменить, иначе они будут продолжать работать for task in pending: task.cancel() В сете done будут таски которые успели завершится, причем как успешно так и нет. 3. До первой ошибки. Тоже самое, но с аргументом FIRST_EXCEPTION done, pending = await asyncio.wait( tasks, return_when=asyncio.FIRST_EXCEPTION ) Функция завершается как только первая задача упадет с ошибкой. Учтите, что в любом случае done вы можете обранужить несколько задач, как с ошибками так и успешные. ↗️ Полный листинг примеров здесь #async

🪐 In the constellation Ophiuchus, the asteroid 101955 Bennu harbors boulders on its surface that are actually fragments from a much larger parent asteroid, dislodged by ancient cosmic impacts. Analysis of samples returned by NASA’s OSIRIS-REx mission revealed minerals that interacted with liquid water billions of years ago, revealing Bennu as a time capsule from the dawn of the solar system. ✨ #Bennu⚡#asteroids⚡#OSIRISRex 👉subscribe Universe Mysteries

🪐 One of the most intriguing potentially hazardous asteroids is (101955) Bennu, a 500-meter-wide space rock that approaches Earth every six years. Bennu's orbit is so well-studied that NASA sent the OSIRIS-REx mission to collect samples, as even small forces—like sunlight changing its spin—can alter its path, making Bennu a prime real-world example of why scientists keep a close watch on these cosmic wanderers. ✨ #asteroids⚡#hazard⚡#Bennu⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐A skyscraper-sized space rock is on its way past Earth. On September 18, 2025, asteroid 2025 FA22, measuring up to 300 meters across, will sweep by our planet. At its closest, it will be about 835,000 km away — more than twice the distance to the Moon. Moving at a breathtaking 34,000 km/h, this Apollo-type asteroid silently follows its orbit around the Sun, crossing Earth’s path in space. The flyby will peak around 07:41 UTC, a moment astronomers worldwide are watching closely. Massive, fast, and ancient — yet passing safely by. Encounters like this remind us how close cosmic giants can come, while still leaving Earth untouched. ✨ #asteroids⚡#hazard⚡#Bennu⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries

🪐 The asteroid Bennu, about 500 meters wide, orbits the Sun and regularly passes close to Earth—so close that it’s classified as a “potentially hazardous asteroid.” Scientists continually monitor Bennu’s path because even small shifts caused by sunlight (known as the Yarkovsky effect) could alter its future trajectory, making it one of the most closely watched objects to help protect our planet from possible impacts. ✨ #asteroid⚡#hazards⚡#Bennu⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries ​

🪐 One of the closest ongoing space threats to Earth is asteroid (101955) Bennu, a 500-meter-wide rock whose orbit brings it near our planet about every six years. Bennu's path is carefully tracked because even small gravitational nudges or sunlight (the Yarkovsky effect, where heat causes tiny pushes) could change its future route, making it a real-world example of why scientists keep a vigilant watch on these near-Earth objects. ✨ #asteroids⚡#defense⚡#Bennu⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​
