【Python】Async异步等待简单例子理解

import time

def run(coroutine):
    try:
        print("")
        coroutine.send(None)
    except StopIteration as e:
        print("e.value",e.value)
        return e.value

async def async_function():
    time.sleep(2)
    print("等待两秒")
    return 1

async def await_coroutine():

    await async_function()
    print("等待执行完成，再执行我")

run(await_coroutine())

# 输出结果

等待两秒
等待执行完成，再执行我
e.value None
