In the steps 4 and 10 for this project, I am a little confused by the syntax for calculating the percentages.

`a_clicks_pivot['percent_clicked =`

is clear enough, we are adding a new column, but for the calculation: `a_clicks_pivot[True] / (a_clicks_pivot[True] + a_clicks_pivot[False])`

, is this just selecting all rows in `a_clicks_pivot`

that have a row where the value equals True?

I don’t immediately see what that `[True]`

part is referencing.
