Rename an object in Google cloud storage

Question

I am trying to rename the cloud storage blob name but after running cloud function there is no change in blob name.

Please find below code:

from google.cloud import storage


def rename_blob(bucket_name, blob_name, new_name):
    
    """Renames a blob."""
    # The ID of your GCS bucket
    # bucket_name = "your-bucket-name"
    # The ID of the GCS object to rename
    # blob_name = "your-object-name"
    # The new ID of the GCS object
    # new_name = "new-object-name"

    storage_client = storage.Client()
    bucket = storage_client.get_bucket(bucket_name)
    blob = bucket.blob(blob_name)

    new_blob = bucket.rename_blob(blob, new_name)

    print("Blob {} has been renamed to {}".format(blob.name, new_blob.name))

if __name__ == "__main__":
  
    rename_blob(etlbucket,test-blob,new-blob)
