24 août 2020 · Cet article présente l’efficacité du MultiIndex par rapport à l’utilisation d’un index classique et les trois méthodes stack, unstack et pivot pour ranger le MultiIndex. Bien manipuler le MultiIndex peut nous aider à réaliser les analyses de données sophistiquées. 1. L’efficacité du MultiIndex.
I have a multi-index data frame with columns 'A' and 'B'. Is there is a way to select rows by filtering on one column of the multi-index without resetting the index to a single column index? For Example.
In this tutorial, you’ll learn about multi-indices for pandas DataFrames and how they arise naturally from groupby operations on real-world data sets. In a previous post, you saw how the groupby operation arises naturally through the lens of the principle of split-apply-combine.
The MultiIndex object is the hierarchical analogue of the standard Index object which typically stores the axis labels in pandas objects. You can think of MultiIndex as an array of tuples where each tuple is unique.
Learn how to create and use MultiIndex in Pandas, a data analysis library for Python. MultiIndex allows us to represent and work with higher-dimensional data efficiently by grouping columns into multiple levels of indexes.
