 This is a small script to cover chaining I've been using chaining for well over a year at work And I just love the way it looks. I think it's very clear So these are just a couple of the commands that I use very often So to filter the data frame I use query when I want to select columns. I use look So here I'm selecting the columns name height and sex Then of course group I where I have as index equal to false I think that makes it downstream processing a little bit more straightforward and Finally, I use a sign to make new columns and With just these these small handful worth of methods. I think that you can get quite a bit done in a very clean way That's it. I guess I can go ahead and show what this data frame looks like real quick Scroll down just a little bit too far That's it. So just three columns I group by sex the height and a boolean for whether That sex is the tallest or not That's all I've got
