When I am looking at the “df”, I notice that there is a “Rev.” in index 886. As a historian, I find this fascinating. Now, I start to wonder, how many reverends were there on the Titanic? Is this individual unique? If I wanted to ask this question outside of Pandas, I could do the following: https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003342175/9c8a9bc9-1828-4190-959b-3289b6805567/content/fig9_2_B.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>
