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.

Happy May 1st, Russian learners! ☀️
In Russia, we say:
• Мир! Труд! Май!
Peace! Labour! May!
But for you, let's change it a little:
• Май! Учёба! Русский!
May! Studying! Russian!
No work today. Just spring, rest, and one small verb conjugation. Maybe two. No pressure.
С праздником! ✨
Natalie with 🤍💙❤️

No Moping Day! Cheerfulness Only Day!

• Унывать (imperf.)
[oo-ny-vat']
Тo mope, to be despondent, to lose heart
Let's remember today's mantra! And NO moping! 💪

• День ответов на вопросы вашей кошки
Answer Your Cat's Questions Day
🔻On this important day, humans attempt to decipher what's really on their feline friend's mind, all in the pursuit of a better life for their whiskered overlord.
😉For example, your cat might be wondering:
👍Почему кормишь одной и той же едой?
Why do you feed me the same food every day?
🔸Почему не выпускаешь на улицу?
Why don't you allow me into the street?
🔸Почему нельзя драть диван?
Why is it not allowed to scratch the sofa?
🔸Где мои бубенчики?
Where are my balls/bells?
❗️What burning questions do you think your fluffy companion would ask you in Russian?
