11/14 Hashes and Symbols..... Why it does not working?


good_movies = {
  memento: 3,
  primer: 3.5,
  the_matrix: 5,
  truman_show: 4,
  red_dawn: 1.5,
  skyfall: 4,
  alex_cross: 2,
  uhf: 1,
  lion_king: 3.5
# Add your code below!

good_movies.select {|name, movie_ratings| movie_ratings > 3}


Error: Oops, try again. It looks like good_movies includes memento, but it shouldn't.

But it is not includes memento when i run the code 

Please help!!


That's because good_movies.select {|name, movie_ratings| movie_ratings > 3} - is what you want, but it's just a copy of good_movies. If you were to call variable good_movies you'd see that it didn't change - it still containt all of the movies. Use bang! methods to modify the original object. In this example - select!. Read about bang methods here.


Thank you, I get it now! :slight_smile:


or assign the temporary hash to a new variable with the code model you have now.

top_rated_movies = good_movies.select { ... }
