AWS Lambda supports Python 3.9 in all regions where Lambda is available from Mid August 2021.

AWS Lambda adds support for Python 3.9

Can you consider to provide 3.9 Layers?

[revmischa]

Sure, what region do you need it in?

eu-central-1

Can I throw a vote / request behind us-west-2 ? 🙏 Thank you !

[quiver]

I think supporting all regions as 3.8 from the start will decrease your workload.

Might need to wait for docker.io/lambci/lambda:build-python3.9 to exist https://hub.docker.com/r/lambci/lambda/tags?page=1&ordering=last_updated

There exists an issue for lambci/lambda:build-python3.9 support.

lambci/docker-lambda#348

Can we now get the support for python 3.9 of this layer is us-east-2?

[revmischa]

We need a docker image to build it with. See https://github.com/lambci/docker-lambda/pull/348 Feel free to send a PR with support for 3.9

Support for python 3.9 us-east-2 would be appreciated

The lambci repository has been inactive, but there is a fork with python3.9 support at https://github.com/mLupine/docker-lambda (discussed here https://github.com/lambci/docker-lambda/issues/353#issuecomment-943301567). Could that be just switched in instead?

That should be sufficient. I've used that specific one for python 3.9 in AWS lambdas w/ successful results

[revmischa]

Cool, I invite anyone to fork this and build for 3.9. Open a PR with your lambda layer ARNs.
