AWS Lambda adds support for Python 3.13 runtime

Amazon Web Services (AWS) has announced the availability of the Python 3.13 runtime for its AWS Lambda service. This expansion enables developers to utilize the newest language features and enhancements when building serverless applications.

The Python 3.13 runtime is available as both a managed runtime and a container base image. Developers can implement Lambda functions using Python 3.13 through the AWS Management Console, AWS Command Line Interface (CLI), AWS SDKs, AWS Serverless Application Model (SAM), and AWS Cloud Development Kit (CDK), alongside other infrastructure as code tools.

Python continues to be a popular choice for serverless application development. The Python 3.13 release incorporates several updates to the language, its implementation, and the standard library. While Python 3.13 includes some experimental features, not all of them are currently available within the Lambda environment.

Support for Python 3.13 extends to Lambda@Edge, allowing for customized content delivery with low latency via Amazon CloudFront. Additionally, developers can integrate with Powertools for AWS Lambda (Python) to enhance observability, error handling, and other functionalities in their serverless applications. The runtime is based on Amazon Linux 2023.
