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.

Benefits of using pandas

pandas forms a core component of the Python data analysis corpus. The distinguishing feature of pandas is that the suite of data structures that it provides is naturally suited to data analysis, primarily the DataFrame and, to a lesser extent, series (1-D vectors) and panel (3D tables).

Simply put, pandas and statstools can be described as Python's answer to R, the data analysis and statistical programming language that provides both data structures, such as R-dataframes, and a rich statistical library for data analysis.

The benefits of pandas compared to using a language such as Java, C, or C++ for data analysis are manifold:

  • Data representation: It can easily represent data in a form that's naturally suited for data analysis via its DataFrame and series data structures in a concise manner. Doing the equivalent in Java/C/C++ requires many lines...
