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.

#Antimicrobials are vital in fighting infectious diseases across humans, animals, and plants.
However, their effectiveness is diminishing, leading to a growing and urgent crisis known as #AntimicrobialResistance.
Let’s promote the responsible use and work together to combat #AMR.
#Handwashing is a basic and effective tool against infections.
If we do not become sick, we would not need to use #antimicrobials.
Encourage your loved ones to practice frequent #handwashing with soap under running water.
Do your part to prevent #AntimicrobialResistance
#Antimicrobials are becoming less effective against common infections in animals & humans.
🚫 Do not self-medicate
✅ Visit a healthcare professional when sick
Everyone has a role to play to ensure #antimicrobials continue to work.

#AntimicrobialResistance is one of the top 10 health threats in the world.
Everyone everywhere, including users and non-users of #antimicrobials have a role to play to prevent #AMR.
#BeAntimicrobialAware
Every year, the National Antimicrobial Resistance Technical Working Group joins the global community to raise awareness of the dangers of misuse or overuse of #antimicrobials.
Fighting #AMR is a global endeavour that must be addressed through a #OneHealth approach as evident in this year's theme of #WAAW2023: ‘Preventing #AntimicrobialResistance together”

Misuse or overuse of #antibiotics💊 & other #antimicrobials can reduce its effectiveness in treating common infections in animals & humans.
From 18th-24th November, we are joining the global health community to mark the annual #WorldAntimicrobialAwarenessWeek2022 .
#StayTuned
#AntimicrobialResistance is when medicines like #antimalarials, tetracycline, septrin, and amoxicillin no longer treat diseases they cured previously.
Everyone everywhere, including users and non-users of #antimicrobials has a role to play to prevent #AMR.
