Is it possible to list all S3 buckets using a boto3 resource, ie boto3.resource('s3')?
I know that it's possible to do so using a low-level service client:
import boto3
boto3.client('s3').list_buckets()
However in an ideal world we can operate at the higher level of resources. Is there a method that allows us to to do and, if not, why?
You can use s3.buckets.all():
s3 = boto3.resource('s3')
for bucket in s3.buckets.all():
print(bucket.name)
Using list comprehension:
s3 = boto3.resource('s3')
buckets = [bucket.name for bucket in s3.buckets.all()]
print(buckets)
Get .buckets.pages() from the S3 resource and then loop through the pages to grab the buckets:
import boto3
buckets_iter = boto3.resource('s3').buckets.pages()
buckets = []
for bucket in buckets_iter:
buckets += bucket
print(buckets)
I hope this helps.
