Mastering pandas - Second Edition

By: Ashish Kumar

Overview of this book

pandas is a popular Python library used by data scientists and analysts worldwide to manipulate and analyze their data. This book presents useful data manipulation techniques in pandas to perform complex data analysis in various domains. An update to our highly successful previous edition with new features, examples, updated code, and more, this book is an in-depth guide to get the most out of pandas for data analysis. Designed for both intermediate users as well as seasoned practitioners, you will learn advanced data manipulation techniques, such as multi-indexing, modifying data structures, and sampling your data, which allow for powerful analysis and help you gain accurate insights from it. With the help of this book, you will apply pandas to different domains, such as Bayesian statistics, predictive analytics, and time series analysis using an example-based approach. And not just that; you will also learn how to prepare powerful, interactive business reports in pandas using the Jupyter notebook. By the end of this book, you will learn how to perform efficient data analysis using pandas on complex data, and become an expert data analyst or data scientist in the process.

Summary

This chapter was a quick tour of the power of NumPy and showed a glimpse of how it makes life easier while working with pandas. Some of the highlights from the chapter were as follows:

  • A NumPy array is a versatile data structure used for containing multidimensional homogeneous data.

  • There are a variety of methods available for slicing/dicing, creating, and manipulating an array in the NumPy package.

  • NumPy arrays have practical applications such as being the building blocks of linear algebra operations and a tool to manipulate multidimensional array data such as images and audio.

  • Arrays (or matrices) are the computational blocks used in advanced mathematical models such as neural networks.

  • NumPy arrays are the precursors of some of the essential data structures in pandas, namely Series.

  • Series are very similar to arrays. Series are one-dimensional. A...
