futures are lazy, tasks are eager (in async python)

future-vs-task.py

import asyncio


async def test(s, n):
    print(f' {s} started')
    await asyncio.sleep(n)
    print(f' {s} ends')


async def main():
    f = test('future', 1)
    t = asyncio.create_task(test('task', 1))

    print('lets wait a bit in main')
    await asyncio.sleep(3)
    print('are we done?')
    await asyncio.gather(f, t)
    print('we are!')

asyncio.run(main())
