title: Upload File to Google Cloud Storage Bucket Sub Directory using Python
body: <p>I have successfully implemented the python function to upload  a file to Google Cloud Storage bucket but I want to add it to a sub-directory (folder) in the bucket and when I try to add it to the bucket name the code fails to find the folder. </p>
  
  <p>Thanks!</p>
  
  <pre><code>def upload_blob(bucket_name, source_file_name, destination_blob_name):
    """Uploads a file to the bucket."""
    storage_client = storage.Client()
    bucket = storage_client.get_bucket(bucket_name +"/folderName") #I tried to add my folder here
    blob = bucket.blob(destination_blob_name)
  
    blob.upload_from_filename(source_file_name)
  
    print('File {} uploaded to {}.'.format(
      source_file_name,
      destination_blob_name))
  </code></pre>
