Python async异步编程获取函数返回值

import asyncio
import time

async def test1():
    lit1=[]
    for i in range(10):
        await asyncio.sleep(3)
        # print(i,"test1")
        lit1.append(i)
    return lit1

async def test2():
    lit2=[]
    for i in range(15):
        await asyncio.sleep(2)
        # print(i,"test2")
        lit2.append(i)
    return lit2

def run():
    start_time = time.time()
    loop = asyncio.get_event_loop()
    task = loop.create_task(test1())
    task1 = loop.create_task(test2())
    loop.run_until_complete(task)
    loop.run_until_complete(task1)
    loop.close()
    print(task.result())
    print(task1.result())
    end_time = time.time()
    print(end_time-start_time)

run()

执行结果:
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14]
