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.

The Sukhothai Kingdom was a Siamese kingdom in Mainland Southeast Asia. It was centered in north-central present-day Thailand. It existed from 1238 to 1438. It later became part of the Ayutthaya Kingdom. The kingdom grew strong under rulers like Si Inthrathit and Ram Khamhaeng. People spoke Old Thai and practiced Theravada Buddhism.

Theravāda Buddhism means “Teaching of the Elders.” It is the oldest surviving school of Buddhism. It follows the Pāli Canon. It teaches the Four Noble Truths: life includes suffering; suffering is caused by craving; suffering can end; the path ends suffering. The Noble Eightfold Path is: right view, right intention, right speech, right action, right livelihood, right effort, right mindfulness, and right concentration. The goal is Nibbāna, freedom from rebirth. Meditation and moral conduct are central practices.

Some Buddhists serve as soldiers even though Buddhism teaches non-violence. Soldiers can protect people, and Buddhism considers the intention behind actions. Actions that reduce suffering can be acceptable according to Buddhist ethics. Concepts like karma and skillful action are important. International humanitarian rules guide soldiers to act carefully. Being a Buddhist does not always mean being completely against war. Martial arts like Kung Fu also connect to Buddhism. They teach discipline, self-control, mindfulness, and protecting others. The goal is training the mind and body, not just fighting.
