You’re great! Lots of vids out there about how to do stuff. Not many about why / in what situations you do the stuff. Thank you!!!

Thanks for such amazing videos. You making learning simple by explaining the functionality and the practical use-cases where the value for that functionality lies. I have a doubt - @6:02 - Shouldn't level be 0 when we are unstacking on the basis of passenger count as this is only row label present ?

Thanks for the kind words! Notice that in many (not all) of the cases in this video, I'm not actually modifying our data frame g. Rather, I'm running a method (e.g., unstack), and getting back a new data frame. This leaves g unchanged, which means that if I first run g.unstack(level=1) and then run g.unstack(level=0), I'm unstacking on the same data frame each time. It's not that after unstacking on level=1 we're left with only one level in the multi-index. Does that make sense?
