Boto3 Version Of List-objects-v2 --query Command In Aws Cli

Would like to know the python boto3 code for below AWS CLI aws s3api list-objects-v2 \ --bucket myBucket \ --prefix path1/path2 \ --query 'reverse(sort_by(Contents,&LastModifie

Solution 1:

The --query capability in the AWS Command-Line Interface (CLI) is a feature of the CLI itself, rather than being performed during an API call.

If you are using the boto3 list_object_v2() command, a full set of results is returned.

You can then use Python to manipulate the results.

It appears that you are wanting to list the most recent object in the bucket/path, so you could use something like:

import boto3

client = boto3.client('s3',region_name='ap-southeast-2')

response = client.list_objects_v2(Bucket='my-bucket')

print (sorted(response['Contents'], key=lambda item: item['LastModified'])[-1])
