Pivoting a DataFrame

You want to convert the Spotify data from long format to wide format in order to compare the number of streams for each artist in each year.

    • Pivot artist_year_df to get the "artist" on each row, the "year" for each column, and the "streams" values.

    • Pivot spotify_df directly where we aggregate by calculating the mean number of streams per artist per year.
