After it’s installed and configured, try using Boto3 to fetch your AWS S3 buckets.

import boto3
s3 = boto3.resource('s3')
for bucket in s3.buckets.all():

Your S3 buckets will be listed after execution.

Boto3 has access to other AWS resources like EC2, meaning you can start and stop instances via Python and Boto3.
