google-cloud-storage version: pip show google-cloud-storage

Name: google-cloud-storage Version: 1.43.0 Summary: Google Cloud Storage API client library Home-page: https://github.com/googleapis/python-storage Author: Google LLC Author-email: googleapis-packages@google.com License: Apache 2.0 Location: /Users/asuleiman/opt/miniconda3/envs/torqata/lib/python3.9/site-packages Requires: six, google-auth, google-resumable-media, google-api-core, requests, google-cloud-core, protobuf Required-by:

Steps to reproduce

Run with delimiter set:

	from google.cloud import storage
	storage_client = storage.Client()
	r = storage_client.list_blobs(bucket_or_name=bucketname,prefix="match/", delimiter='/')
	c = 0
	for blob in r:
		print(blob.name)
		c+=1
		if c > 5:
			break

Result:

empty

Run without delimiter set:

	from google.cloud import storage
	storage_client = storage.Client()
	r = storage_client.list_blobs(bucket_or_name=bucketname,prefix="match/",)
	c = 0
	for blob in r:
		print(blob.name)
		c+=1
		if c > 5:
			break

Result:

Thanks for the question @ali-suleiman-44b20b39

If you specify both prefix and delimiter, you'll get back only the files directly under the prefix/. As part of the response, you'll also get back an r.prefixes entity that lists the "subfolders" under the prefix/. Please refer to the API doc.

You can try adding a block of code if you want to view the subdirectories


r = storage_client.list_blobs(bucket_or_name=bucketname,prefix="match/", delimiter='/')

if r.prefixes:
    print("prefixes list includes:")
    for sub in r.prefixes:
        print(sub)

I see it in the comment lines here: https://cloud.google.com/storage/docs/listing-objects#storage-list-objects-python I will try this out. Thanks

Great, closing the issue for now. Feel free to reopen if you have further questions. Thanks!
