using Python 3 with AWS lambda

Question

Can one use application built with Python3 in lambda, and not just python2.7. Possibly looking at options around - https://gun.io/blog/announcing-zappa-serverless-python-aws-lam

Answer 1

Python 3.6 is now available in Ohio! (us-east-2)

I ran:

def lambda_handler(event, context):
    # TODO implement
    return sys.version

And it kicked back:

"3.6.1 (default, Mar 27 2017, 23:56:45) \n[GCC 4.9.3]"

Answer 2

Lambda functions run in a container on a well-known AMI. While you must handle the initial event with Python2.7, you can call out to anything installed on the AMI. In particular, Python3 is already installed. It's a bit complicated, but you can establish a virtualenv to take advantage of the installed python3.

For a few of the details, see http://www.cloudtrek.com.au/blog/running-python-3-on-aws-lambda/.

Answer 3

Change runtime language to python version 3. https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html

Answer 4

You can use Python 3 with aws lambda. when you are creating an Aws lambda function there is an option where you can use a python 3 as a version and execute your code.

Answer 5

Python 3.6 is now fully supported by Lambda.
