Let's head over to the Jupyter Notebook to look at a couple of examples. Let's reuse the ATH data frame that we created in the previous video. So ath.head gives us the first couple of rows.

And let's see what changes we see to the ATH data frame. And we can see that the athlete is now the index for the data frame. And this…
