Serverless[0] does support Python (the CLI tools are just written in JS). Zappa[1] is also a great option if you want to deploy a WSGI compatible app (flask/django) to Lambda.

I've used them both in production and have had a great experience.

AWS Lambda supports:

* Node.js – v4.3.2 * Java – Java 8 * Python – Python 2.7 * .NET Core – .NET Core 1.0.1 (C#)

The Serverless framework is predominantly geared towards node and I believe Python, and making it simple to deploy not just to AWS Lambda but IBM's OpenWhisk FaaS. Google has a FaaS in closed beta at the moment - Google Cloud Function - that is also Node and Python.

I'm expecting all of them to support Go and Ruby as first class citizens by the end of the year.
