1.Problem Statement:

I have s3 bucket and N number of files as objects inside the bucket. I want to get the all the object keys using a lambda in python.

Lambda Function:

              import json 
              import boto3 
              from botocore.exceptions import ClientError
              import csv
              from datatime import datatime
              import logging
              from os import listdir

              s3 = boto3.cleint('s3')
              Count = 1
              Def lambda_handler(event,context):
              Keys = []
              resp = s3.list_objects_v2(Bucket='testbucket')
              for obj in resp['Contents']:
              Print("keys are")
              return {
                'files_array' :keys ,
              'bucket' : 'testbucket'

In the above lambda , first the list of all the objects as ‘resp’ And looping the ‘resp’ and printing the keys.
