python asyncio add_done_callback with async def

Question

I have 2 functions: The first one, def_a, is an asynchronous function and the second one is def_b which is a regular function and called with the r

Answer 1

This only works for one future job, if you have multiple async jobs, they will blocks each other, a better way is using asyncio.as_comleted() to iterate future list:

import asyncio

async def __after_done_callback(future_result):
    # await for something...
    pass

async def __future_job(number):
    await some_async_work(number)
    return number + 1

loop = asyncio.get_event_loop()
tasks = [asyncio.ensure_future(__future_job(x)) for x in range(100)]  # create 100 future jobs

for f in asyncio.as_completed(tasks):
    result = await f
    await __after_done_callback(result)

loop.close()
