Lab - Python Challenge

In this lab, you get hands-on experience testing your Python skills by updating application code for AWS Lambda functions that read and write directly from and to an Amazon DynamoDB table.

Objectives

   •   Understand the AWS SDK for Python (Boto3) client code for DynamoDB in the application files.

   •   Update a Python application to PUT customer details into a DynamoDB table.

   •   Use Python code to update a DynamoDB table with parameters that are retrieved from an API Gateway request.

Prerequisites

   •   You should have already completed the Integrating Amazon DynamoDB lab (SPL-BE-100-CEIADD-1). It teaches the fundamentals that are required to complete this challenge on your own, instead of using hints and a solution file.

   •   Familiarity with the basic navigation of the AWS Management Console.

   •   Versed in editing and running Python scripts by using an AWS Cloud9 code editor and terminal.

   •   A basic understanding and familiarity with Amazon API Gateway, AWS SAM, AWS Lambda, and AWS CloudFormation.

   •   Prior experience with AWS services and serverless computing is helpful, but not necessarily required.

Outline

Task 1: Review the Amazon S3 hosted website and access the AWS Cloud9 environment

Challenge A: Update the application

Task 2: Deploy the updates and test
