Detailed explanations help guide your success and make your new skills stick. You’ll even get a big boost to productivity, with tasks that used to mean a trip to StackOverflow now a natural part of your skillset.

Pandas approaches problems differently than Python. The syntax is the same, but the data structures are different, and the way you structure your solutions is also different. Pandas is so vast that it’s easy to lose track of all the techniques. And unlike the core Python language, which tries to adhere to the maxim “There should be only one way to do it,” there are often many ways to accomplish the same task in pandas. Knowing which of these ways is fastest to execute and easiest to maintain isn’t always obvious, even (or especially) if you’re an experienced Python developer.
