Certainly! Below is a step-by-step tutorial on how to read a JSON file from an Amazon S3 bucket using AWS Lambda and Python. We'll go through setting up the AWS Lambda function, configuring the necessary permissions, and writing the Python code to read the JSON file.
AWS Account: Make sure you have an AWS account.
AWS CLI: Install and configure the AWS CLI on your local machine.
