Boto3 S3, sort bucket by last modified

Question

I need to fetch a list of items from S3 using Boto3, but instead of returning default sort order (descending) I want it to return it via reverse order.

I know you ca

Answer 1

A simpler approach, using the python3 sorted() function:

import boto3
s3 = boto3.resource('s3')

myBucket = s3.Bucket('name')

def obj_last_modified(myobj):
    return myobj.last_modified

sortedObjects = sorted(myBucket.objects.all(), key=obj_last_modified, reverse=True)

you now have a reverse sorted list, sorted by the 'last_modified' attribute of each Object.
