input: Write a python function to create a TVShow object and retrieve its title, season number, episode number, and rating.
  ```python
  def test_tvshow():
    show = TVShow("Breaking Bad", 5, 14, 9.5)
    assert show.get_title() == "Breaking Bad"
    assert show.get_season_number() == 5
    assert show.get_episode_number() == 14
    assert show.get_rating() == 9.5
  
    show2 = TVShow("Game of Thrones", 8, 6, 8.1)
    assert show2.get_title() == "Game of Thrones"
    assert show2.get_season_number() == 8
    assert show2.get_episode_number() == 6
    assert show2.get_rating() == 8.1
output: class TVShow:
      def __init__(self, title, season_number, episode_number, rating):
          self.title = title
          self.season_number = season_number
          self.episode_number = episode_number
