What do I do here since I can't use iloc?

(can’t post github url here)

I’m being a bit lazy here as I have Alteryx, Tableau, UI Path, Dask and my last course at my masters this month so if you don’t mind and have time, please feel free to help.

It seems you trie to post several messages with a github link and Discourse has blocked you. Not sure if I am authorised to correct this.
