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.

El exjugador de Barça, Bayern, Liverpool y España ha tomado su decisión.
La pasión y el amor de Thiago por el juego continúan mientras está listo para un nuevo capítulo en el fútbol después de algunos meses de planificación.

Lara, speaking from Brazil, has had no contact with her husband, Thiago Ávila, since he was abducted and detained illegally by Israeli forces from the 'Madleen'. Since then, Thiago has been placed in solitary confinement, denied communication with his family.
According to Lara, Israeli authorities threatened Thiago with the psychological torment of isolation without light or ventilation. Despite this, Thiago remains on hunger strike, holding firm to his belief in justice for Palestinians and the right of every child to food, safety, and freedom.
From his prison cell, he wrote a letter to his 1-year-old daughter. Lara generously shares that with us today.
This is a call not just for Thiago’s release—but for the world to pay attention to Gaza, to Palestine, and to all people who are exploited, forced to live under occupation.

"Families of Gaza are not less important than my family. It’s by mere chance that we are not one of those families that are in Gaza right now."
Thiago Ávila, father and activist aboard 'Handala', will sail towards Gaza with an urgent mission: to break the illegal siege and stand with the children of Gaza. 'Handala' is a small boat, but it carries the weight of a global uprising for justice. As catastrophic famine unfolds across Gaza, evidence of heinous sexual and physical violence by the IOF continues to emerge, and the Israeli and U.S.-backed genocide persists with impunity, people power is more integral than ever—it’s up to us to shape a new society.
The world must not turn its eyes away. Keep your eyes on 'Handala'. Share our mission, amplify Palestinian voices, and do everything you can to stand for Gaza. The flood of change is coming—be part of it. #FreedomFlotilla#Handala#FreePalestine#Gaza#AllEyesOnDeck#FreeGaza#WeWillSail#Thiago#Brazil#HumanRights#Genocide#IOF
