List all secrets in gnome-keyring. Somewhat like secret-tool search --all where you don't have to specify any attributes.

searchallpw.py

import gi
gi.require_version('Secret', '1')
from gi.repository import Secret
for item in Secret.password_search_sync(None, {}, Secret.SearchFlags.ALL, None):
    print(f'attributes {item.get_attributes()}')
    print(f'label {item.get_label()}')
    print(f'secret {item.retrieve_secret_sync().get()}')
