How to download Wasabi/S3 object to file using boto3 in Python

You can use boto3’s download_fileobj() in order to download files from S3 to the local filesystem:

with open("myfile.txt", "wb") as outfile:
    my_bucket.download_fileobj("myfile.txt", outfile)

Note that the file needs to be opened in binary mode ("wb").

Full example

import boto3

# Create connection to Wasabi / S3
s3 = boto3.resource('s3',
    endpoint_url = '',
    aws_access_key_id = 'MY_ACCESS_KEY',
    aws_secret_access_key = 'MY_SECRET_KEY'

# Get bucket object
my_bucket = s3.Bucket('boto-test')

# Download remote object "myfile.txt" to local file "test.txt"
my_bucket.download_file("myfile.txt", "test.txt")

Don’t forget to fill in MY_ACCESS_KEY and MY_SECRET_KEY. Depending on what region and what S3-compatible service you use, you might need to use another endpoint URL instead of
