BEGIN;
DROP EXTENSION plpython3u;
ROLLBACK;

If you can drop the extension, no objects depend on it.

For example, that will show if there are any PL/Python functions defined.

If you want to know if PL/Python functions are used, monitor
"pg_stat_user_functions" (after enabling "track_functions") and see if
the number of calls is growing.
