Treehouse TeacherHi! The query you have already holds all of the romance movies, so you just need to set it equal to the variable name.
romance_movies = session.query(Movie).filter_by(genre=='Romance')
Right now your for loop
is overriding the variable with a new movie each time. For example, if the movies it returned were 'The Notebook', 'Romancing the Stone', and 'Titanic'. The loop will grab the first movie, 'The Notebook' and set it equal to the variable, then it will grab the next one, 'Romancing the Stone', and set the variable to now equal this movie, and finally, it will grab the last movie, 'Titanic', and set the variable equal to this last movie. So at the end of the loop, the variable equals the final movie, 'Titanic', instead of the whole list of movies.
