Description

This is a ‘reticulated’ wrapper for the ‘Python’ ‘boto3’ ‘AWS’ ‘S3’ client library https://boto3.readthedocs.io/en/latest/reference/services/s3.html. It requires ‘Python’ version 3.5+ and an ‘AWS’ account.

What’s Inside The Tin

• download_file: Download an S3 object to a file
• upload_file: Upload a file to an S3 object
• file_exists: Test if a file exists in the specified bucket
