Problem Statement − Use boto3 library in Python to get a list of files from S3, those are modified after a given date timestamp.Example − List out test.zip from Bucket_1/testfolder of S3 if it is modified after 2021-01-21 13:19:56.986445+00:00.Approach/Algorithm to solve this problemStep 1 − Import boto3 and botocore exceptions to handle exceptions.Step 2 − s3_path and last_modified_timestamp are the two parameters in function list_all_objects_based_on_last_modified. "last_modified_timestamp" should be in the format “2021-01-22 13:19:56.986445+00:00”. By default, boto3 understands the UTC timezone irrespective of geographical location.Step 3 − Validate the s3_path is passed in AWS format as s3://bucket_name/key.Step 4 − Create an ... Read More
Problem Statement − Use boto3 library in Python to download an object from S3 at a given local path/default path with overwrite existing file as true. For example, download test.zip from Bucket_1/testfolder of S3.Approach/Algorithm to solve this problemStep 1 − Import boto3 and botocore exceptions to handle exceptions.Step 2 − From pathlib, import Path to check filenameStep 3 − s3_path, localpath and overwrite_existing_file are the three parameters in the function download_object_from_s3Step 4 − Validate the s3_path is passed in AWS format as s3://bucket_name/key. By default, localpath = None and overwrite_existing_file = True. User can pass these values as well to ... Read More
