This document explains the usage of the Python function files_in_bucket, which can be used to list files within a specific folder in a Google Cloud Storage bucket.

Parameters:

1. bucket_name (str): The name of the Google Cloud Storage bucket.

2. folder_name (str): The name of the folder within the bucket to list files from.

3. filename_needed (bool, optional): Defaults to True. If True, returns a list of filenames.

4. file_object_needed (bool, optional): Defaults to False. If True, returns a list of file objects.

5. list_sub_folders (bool, optional): Defaults to False. If True, includes files from subfolders within the specified folder.

Return Value:

1. A list of filenames (strings) if filename_needed is True.
2. A list of file objects, which can further be used to extract different aspects of the contained file, if file_object_needed is True.
3. None if both filename_needed and file_object_needed are False.
4. Raises an exception if an error occurs.

Example Usage:

Python:

from google.cloud import storage

bucket_name = "my-bucket" folder_name = "data/"

Get filenames only

filenames = files_in_bucket(bucket_name, folder_name) print(filenames)

Get file objects only

file_objects = files_in_bucket(bucket_name, folder_name, file_object_needed=True) for blob in file_objects: print(blob.name)

Include files from subfolders

all_files = files_in_bucket(bucket_name, folder_name, list_sub_folders=True) print(all_files)

Additional Notes:

1. This function requires the google-cloud-storage library to be installed.
2. Ensure you have proper authentication set up to access the specified bucket.
3. The function includes basic error handling, but you may want to implement more specific handling based on your needs.
