What is the correct way to write asyncio code for use with AWS Lambda?

Question

I wrote the following code:

import asyncio

loop = asyncio.get_event_loop()

async def get_urls(event):

    return {'msg':'Hello World'}

def lambda_handler(event,context):

    return loop.run_until_complete(get_urls(event))

I was trying to accomplish the following but faster.

def lambda_handler(event, context):
    # TODO implement
    return {'msg':'Hello World'}

What was the correct way to write this in an AWS Lambda environment?

Works for me... You need to choose Runtime "Python 3.6" or "Python 3.7".

import asyncio

loop = asyncio.get_event_loop()

async def get_urls(event):
    return {'msg':'Hello World'}

def lambda_handler(event, context):
    return loop.run_until_complete(get_urls(event))
