Example code from client quickstart not working

[caliph007]

I hope I am not fully making a fool of myself.
I am not able to get to work the few lines of the client quickstart code:

import aiohttp
async with aiohttp.ClientSession() as session:
    async with session.get('http://httpbin.org/get') as resp:
        print(resp.status)
        print(await resp.text())

in Python 3.6. I get:

async with aiohttp.ClientSession() as session:
SyntaxError: invalid syntax

That I understand, because async became a reserved work in 3.7.
But the doc states as dependency Python 3.5.3+

in Python 3.7 I get:

async with aiohttp.ClientSession() as session:
SyntaxError: 'async with' outside async function

What am I doing wrong?
Thank you in advance.

GitMate.io thinks the contributor most likely able to help you is @asvetlov.

Possibly related issues are #3175 (aiohttp client timeout does not work), #1309 (Client Tracing), #556 (Example in readme doesn't work as is), #1640 ( Readme client example throws an AssertionError), and #3234 (NameError during WebSockets example in Web Server quickstart docs).

@caliph007 You can't use async code without loop.

Full example of code in Python 3.5-3.6:

import asyncio
import aiohttp


async def main():
    async with aiohttp.ClientSession() as session:
        async with session.get('http://httpbin.org/get') as resp:
            print(resp.status)
            print(await resp.text())

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

Full example of code in Python 3.7

import asyncio
import aiohttp


async def main():
    async with aiohttp.ClientSession() as session:
        async with session.get('http://httpbin.org/get') as resp:
            print(resp.status)
            print(await resp.text())

asyncio.run(main())

[asvetlov]

await can be used inside async def function only.
This is not an aiohttp issue at all

I think this issue should be reopened. The client quickstart https://docs.aiohttp.org/en/stable/client_quickstart.html has examples that don't work, as @caliph007 noted above
