read file from s3 python
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()
