Stack and unstack are useful methods that let you reorganize your data frame. But I've found that they're really hard for many people to understand. Which isn't a surprise, given most of the explanations I've seen.
In this video, I show you what stack and unstack do, how to use them, and also why you would use them. You'll see that they're easy to understand and work with, and super useful when you have multi-indexes on your data frames.
There's a small bug in the video, by the way: I tell you not to use inplace=True. But there is no inplace=True for stack and unstack! I'm so used to telling people not to use this keyword argument that I got carried away. Whoops!
