初学 python,大家帮忙看看这段协程代码，运行结果想了半天还没想通

import logging; logging.basicConfig(level=logging.INFO)

import asyncio, os, json, time
from datetime import datetime

from aiohttp import web

def index(request):
    logging.info('server response...')
    return web.Response(body=b'<h1>Awesome</h1>')

async def init(loop):
    app = web.Application(loop=loop)
    app.router.add_route('GET', '/', index)
    logging.info('server before...')
    srv = await loop.create_server(app.make_handler(), '127.0.0.1', 9000)
    logging.info('server started at http://127.0.0.1:9000...')
    return srv

loop = asyncio.get_event_loop()
loop.run_until_complete(init(loop))
loop.run_forever()

我觉得运行的日志：

INFO:root:server before...
INFO:root:server response...
INFO:root:server started at http://127.0.0.1:9000...

结果正确的日志是：

INFO:root:server before...
INFO:root:server started at http://127.0.0.1:9000...
INFO:root:server response...

在我的理解里， python 执行到 await 应该暂停执行函数， TCP 协程结束后，才执行 server started at...这条日志。怎么函数一下子全部执行完了。
