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.

Vegan diets can help the environment, but large-scale plant farming can hurt soil, wildlife, and cause pollution. Synthetic fertilizers used in farming can damage oceans and soil. Animal farming done the right way helps soil, supports wildlife, and uses natural manure. Eating animal foods gives important nutrients like B12 and iron that plants don’t provide.

A single tree, called the Tree of 40 Fruits, holds the record for the most varieties of fruit on one tree. Created by Sam Van Aken, it has 40 different types of stone fruits. These include peaches, plums, apricots, almonds, and cherries. The tree was made using grafting, where branches from different fruit trees are attached to one rootstock. This project shows how diverse fruit can grow on a single tree.

Hussam Saraf set a record for the most species grafted onto a single tree. His tree has 5 different species: plum, apricot, almond, peach, and cherry. The tree was made by grafting branches from these species onto one trunk. This represents diversity and peaceful coexistence, as the fruits symbolize how different cultures can live together.
