Amazon Web Services provides Boto3 S3 SDK for Python. The Boto3 SDK provides methods for uploading and downloading files from S3 buckets.
In this tutorial, you will learn how to download files from S3 using the AWS Boto3 SDK in Python.
Install the latest version of Boto3 S3 SDK using the following command:
pip install boto3
To download files from S3, use download_fileobj(bucket, key, filename) method that downloads a file as an object to a file-like object.
import boto3 from botocore.exceptions import ClientError s3_client = boto3.client('s3', region_name='us-east-1', aws_access_key_id=ACCESS_KEY, aws_secret_access_key=ACCESS_SECRET) def download_my_file(bucket, folder, file_name): key = key = folder+"/"+file_name with open(file_name, 'wb') as f: s3_client.download_fileobj(bucket, key, f) #Downloading file download_my_file("bucket-name", "download-from-subfolder-name", "test.html")
