Meet the hardest functions of Pandas

Meet the hardest functions of Pandas

Meet the hardest functions of Pandas. Master the when and how of pivot_table() , stack() , unstack().

Introduction

Here is the worst-case scenario: You are watching a paid course and the instructor is talking about a certain topic. Then, all of sudden, he introduces a completely new function saying “This function/method is perfect in this case, it is very easy so just check out its documentation for more details”. You say OK, go to the documentation, and don’t even know what you are looking at.

You feel frustrated, go to read some articles or StackOverflow threads, and sometimes come back feeling even worse. Believe me, that happens to everyone. This article is specifically about the case of hard pandas functions.

Mostly, the reason why most sources do not cover some advanced functions of pandas is that they are very case-specific. When you learn the basic methods and functions, you learn them in their own context like on toy datasets. For harder functions, they are difficult to explain, and would be hard to create the context they are useful in.

Such functions are often in the toolbox of more experienced scientists. They make the difference where you use them in such a way that the function solves the problem you are having with one line of code so elegantly. This post is about the three of them: pivot_table()stack() and unstack().
