How to use boto3 to iterate ALL objects in a Wasabi / S3 bucket in Python

This snippet shows you how to iterate over all objects in a bucket:

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')

# Iterate over objects in bucket
for obj in my_bucket.objects.all():

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

Example output:

s3.ObjectSummary(bucket_name='boto-test', key='10k-Test-Objects/1.txt')
s3.ObjectSummary(bucket_name='boto-test', key='10k-Test-Objects/10.txt')
s3.ObjectSummary(bucket_name='boto-test', key='10k-Test-Objects/100.txt')
