1. Read in the movie dataset, and use the set_index method to set the title of each movie as the new index:

>>> movie = pd.read_csv('data/movie.csv')
>>> movie2 = movie.set_index('movie_title')
>>> movie2

2. Alternatively, it is possible to choose a column as the index upon initial read with the index_col parameter of the read_csv function:

>>> movie = pd.read_csv('data/movie.csv', index_col='movie_title')
