Sample code demonstrating use of await with concurrent.futures

async_await_sample.py

from concurrent.futures import ThreadPoolExecutor, Future
import asyncio
import time

async def sum_numbers(x, y):
    await asyncio.sleep(1)
    return x + y

def sum_numbers_blocking(x, y):
    time.sleep(1)
    return x + y

async def print_sums():
    result = await sum_numbers(1, 2)
    print('sum 1: %d' % result)

    result = await executor.submit(sum_numbers_blocking, 3, 4)
    print('sum 2: %s' % result)

executor = ThreadPoolExecutor()
loop = asyncio.get_event_loop()
loop.run_until_complete(print_sums())
loop.close()
