input: Write a function to design a class in Python for storing movie information including the name, year of release, genre, and rating. The class should have an __init__ method to initialize these attributes. Return an instance of this class with "Interstellar", 2014, "Sci-Fi", and 8.4 as parameters.
  assert Movie("Interstellar", 2014, "Sci-Fi", 8.4).name=="Interstellar"
  assert Movie("Interstellar", 2014, "Sci-Fi", 8.4).release_year==2014
  assert Movie("Interstellar", 2014, "Sci-Fi", 8.4).genre=="Sci-Fi"
  assert Movie("Interstellar", 2014, "Sci-Fi", 8.4).rating==8.4
  assert Movie(name="The Matrix", release_year=1999, genre="Action", rating=8.7).name=="The Matrix"
  assert Movie(name="The Matrix", release_year=1999, genre="Action", rating=8.7).release_year==1999
  assert Movie(name="The Matrix", release_year=1999, genre="Action", rating=8.7).genre=="Action"
  assert Movie(name="The Matrix", release_year=1999, genre="Action", rating=8.7).rating==8.7
output: class Movie:
      def __init__(self, name, release_year, genre, rating):
          self.name = name
          self.release_year = release_year
          self.genre = genre
          self.rating = rating
