boto3 offers a resource model that makes tasks like iterating through objects easier. Unfortunately, StreamingBody doesn't provide readline or readlines. s3 = boto3.resource('s3') bucket = s3.Bucket('test-bucket') # Iterates through all the objects, doing the pagination for you. Each obj # is an ObjectSummary, so it doesn't contain the body. You'll need to call # get to get the whole body. for obj in bucket.objects.all(): key = obj.key body = obj.get()['Body'].read()
get files from s3 bucket python
import boto3 import botocore BUCKET_NAME = 'my-bucket' # replace with your bucket name KEY = 'my_image_in_s3.jpg' # replace with your object key s3 = boto3.resource('s3') try: s3.Bucket(BUCKET_NAME).download_file(KEY, 'my_local_image.jpg') except botocore.exceptions.ClientError as e: if e.response['Error']['Code'] == "404": print("The object does not exist.") else: raise
