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.

Trump’s America First Doctrine: Back to the Future, With More Guns
President Donald Trump’s overnight raid in Venezuela marks a bold revival of U.S. dominance in the Western Hemisphere—dubbed the so-called “Donroe Doctrine” by the White House, a Trumpian twist on Monroe’s original. The message is clear: the Americas are America’s backyard, and the rules are being rewritten for the 21st century.
"The goal of the policy is to see changes in Venezuela that are beneficial to the United States first and foremost,"
said Secretary of State Marco Rubio, framing the intervention as a win for both Washington and the Venezuelan people.
But the strategy is a double-edged sword. While Trump’s team promises stability, critics warn of unintended consequences: Russia and China may feel freer to flex their muscles elsewhere, and smaller nations could start hedging their bets by looking for new allies. The U.S. is not just flexing power—it’s also sending a signal that might backfire in the long run.
Trump’s vision extends beyond Venezuela. He’s revived talk of taking over Greenland, threatened Cuba, and even floated the idea of annexing Canada. But allies aren’t buying it. Denmark’s prime minister dismissed Trump’s threats as “nonsensical,” urging the U.S. to stop pressuring close allies.
So is this a return to the glory days of American empire, or just a risky game of geopolitical poker? One thing’s certain: the world is watching, and the stakes are higher than ever.
