I am trying to search if a folder exists within a parent folder

My code returns all items in the parent folder

parentFolder=folder = user_client_archive.folder(folder_id=mainFolderID).get()
                               print("Parent Folder "+parentFolder.name)
                               items = user_client_archive.search().query(query='MyFolder_NoCollab',ancestor_folders=iparentFolder],content_types=o'name',])
                               for item in items:
                                    print(f'The item ID is {item.id} and the item name is {item.name}')
