Python 协程 BUG？

import asyncio
import aiohttp
async with aiohttp.ClientSession() as session:
    async with session.get('https://api.github.com/events') as resp:
        print(resp.status)
        print(await resp.text())
-------------
  File "/Users/zed/PycharmProjects/example/used_aiohttp/1.py", line 3
    async with aiohttp.ClientSession() as session:
             ^
SyntaxError: invalid syntax

现在是不支持这样的写法了吗

async with xxxxx as xxxx:
    pass

aiohttp

Async

@freestyle 包起来是可以的
但是看官网的示例是这么写的，还以为是我的姿势不对。。

```
import asyncio
import aiohttp

async def fetch():
async with aiohttp.ClientSession() as session:
async with session.get('https://api.github.com/events') as r:
print(r.status)
print(await r.text())

loop = asyncio.get_event_loop()
loop.run_until_complete(fetch())
loop.close()
```
我估计官网是默认你会用 asyncio

其实我觉得挺需要一个 apython 直接在 async def 环境内执行. py 文件

要写在 async def 内
