Deleting a single document
No collection stays perfect forever. Sometimes, you'll need to remove outdated, invalid, or unwanted entries. MongoDB makes this easy with .delete_one(), which removes the first matching document based on a filter. In this exercise, you'll remove the movie Casablanca from the collection. It's no longer needed in our dataset. No pre-written code is available this time; you've got this!
