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 some places, coastal cliffs are vanishing so quickly that entire villages have moved inland within a single generation, as sea level rise and stronger storms speed up the erosion. ✨ #erosion⚡#coastlines⚡#climate⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 The boundary where the Earth's solid land meets the sea—called the coastline—is constantly changing. Waves, tides, and storms reshape these edges every day, making coastlines dynamic and ever-shifting. ✨ #geography⚡#coastlines⚡#change⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 Coastal erosion is eating away cliffs and beaches so fast in some places that detailed maps need updating every year, with new shorelines appearing and disappearing before our eyes. ✨ #coastlines⚡#erosion⚡#mapping⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 Coastal erosion now removes up to 24 square meters of land per meter of shoreline in some parts of West Africa each year, forcing whole fishing villages to move further inland. ✨ #coastlines⚡#erosion⚡#sea-level ⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 Satellite data shows that some coastlines have retreated by over 50 meters in just a decade, as rising sea levels and stronger storms rapidly reshape shores across the globe. ✨ #erosion⚡#sea-level ⚡#coastlines⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 The Mediterranean coastline holds more than 150 million-year-old fossils, often exposed in seaside cliffs by constant wave erosion. Some beach rocks here contain ancient traces of life dating back to the dinosaurs. ✨ #coastlines⚡#fossils⚡#erosion⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 Mangroves protect coastlines from storms and rising seas, but over a third have been lost worldwide. Their destruction leaves many regions more vulnerable to flooding and erosion. ✨ #mangroves⚡#coastlines⚡#erosion⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 The Salar de Uyuni in Bolivia holds an ancient, dried-up sea that now forms the world's largest salt flat. Rare rainy seasons briefly transform it into a mirror reflecting the entire sky. ✨ #coastlines⚡#saltflat⚡#landscape⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 The Bohai Sea in China is so shallow that its average depth is just 18 meters—less than a six-story building. This makes it one of the least deep seas in the world’s coastal regions. ✨ #seas⚡#coastlines⚡#shallow⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels
