Joining on index

Your team has decided to take advantage of multi-level indexes for data frames. A colleague has reloaded the game_matchups and punts data frames. This time, each data frame has its key column(s) as the index.

You want to rejoin the data frames by index and compare the percentage of punts by quarter for 2016 and 2017.
