asyncio.gather 를 사용하자
- java completion executor 와 같은 동시성 제공.., 결과 끝날때까지 기다림, 코루틴 결과 취합가능함
import asyncio
import time
async def say_after(delay, what):
await asyncio.sleep(delay)
print(what)
return delay
async def main():
print(f"started at {time.strftime('%X')}")
# task1 = asyncio.create_task(
# say_after(1, 'hello'))
#
# task2 = asyncio.create_task(
# say_after(2, 'world'))
t = await asyncio.gather(
say_after(1,'hello')
,say_after(2, 'world')
)
print(t)
# Wait until both tasks are completed (should take
# around 2 seconds.)
# await task1
# await task2
print(f"finished at {time.strftime('%X')}")
asyncio.run(main())
