    Course Notes

    Use this workspace to take notes, store code snippets, or build your own interactive cheatsheet! For courses that use data, the datasets will be available in the datasets folder.

    df_m = pd.read_csv('/work/files/workspace/datasets/movies.csv')
    df_u = pd.read_csv('/work/files/workspace/datasets/user_ratings.csv')
    
    df_m.head()
