Unless… you meant “how to a create empty folder within GCS bucket”. If so, you can achieve that e.g. by explicitly creating an object with trailing slash in name:

gcp.storage.BucketObject(
    "empty-folder",
    bucket=my_bucket_name,
    name='example_folder/',
    content='IT-DOES-NOT-MATTER',
)

content

field is required but it will be ignored in case object has trailing slash in name. Just a reminder, GCS (and basically most of object storage solutions) uses a flat filesystem. That means, you don’t have to actually create empty folders in order to store things within them. You can directly upload file

parent_folder/subfolder/myfile.txt

and it will “create” parent directories automatically (cause in fact, it’s just a long name with slashes and not a real tree-like structure).
