Python Lambda Function Example: A Hands-On Guide
A recent article on Dev.to highlights a Python Lambda function example, showcasing its capabilities and applications. The code snippet demonstrates how to create a thumbnail of an image uploaded to Amazon S3 using the AWS SDK for Python (Boto3). The lambda function extracts information from the event, downloads the image, processes it with Pillow, and uploads the thumbnail back to S3.

This hands-on guide provides a step-by-step explanation of the important parts, including creating an S3 client, handling events, extracting bucket and key information, downloading and processing images, and uploading thumbnails. The article also touches on Lambda layers, which can package dependencies, custom runtimes, or configuration files for easier deployment and management.
