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.

Lassa fever (LF) initially presents like other common illnesses accompanied by a fever, such as malaria.
Healthcare workers are urged to remain vigilant.
Consider a #LF diagnosis when seeing patients showing symptoms of fever.

Healthcare workers should raise suspicion for patients with a history of contact with
➡️a probable/confirmed case of #LassaFever within 21 days of onset of fever
➡️body fluids/tissues of a patient with a febrile illness, symptoms & signs suggestive of #LF

Healthcare workers are advised to always be vigilant - lookout for symptoms of #LassaFever, not all fevers are malaria.
Any febrile illness that has not responded to the use of anti-malaria or antibiotics after 48 hrs should raise an index of suspicion for #LF.
