This lesson expands your AWS S3 knowledge to include managing objects (files) within buckets. We'll explore uploading, downloading, and deleting objects with Boto3, focusing on real-world applications like user uploads or maintaining an image archive.

For simplicity, we'll use Boto3's resource interface. Specify the bucket (cosmo-user-uploads), the object name within the bucket (cosmo-profile-2023.jpg), and the file's local path to upload.

To efficiently manage data within S3 buckets, understanding how to list the objects stored is crucial. This capability enables tracking and organizing stored content, facilitating operations like batch processing or clean-up. Boto3's resource interface provides a straightforward method to enumerate objects in a bucket.

In this snippet, cosmo-user-uploads represents the bucket name. The loop iterates over each object in the bucket, printing the object's key (name).

To download files, specify the bucket, the object's key, and the local save path.
