[FIXED] Use await in python REPL directly

Issue

I am wondering if there is a way to call async functions with await directly from python REPL ?

So having following code as example:

import aiohttp
import asyncio


async def somefunc():
    async with aiohttp.ClientSession() as session:
        host_url = 'https://somehost'
        async with session.get(host_url) as resp:
            response = await resp.json()
        return response

What I am looking for is an easy way to debug similar functions, basically I'd like to

>>> result = await somefunc()

I am aware that this can be done with

import asyncio

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

But using this approach I would need to either alter the body of somefunc to log the result of the response or use additional async function such as below to print the result

async def result_print():
    result = await somefunc()
    print(result)

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

Summarising the things above, I am looking for a more convenient way to await async functions in the python REPL, maybe a custom REPL implementation that allows

>>> result = await somefunc()

Or possible there's a way to do that in python default repl that I am not aware of ?

Solution

The behavior you want is available if you launch the REPL using

python -m asyncio
