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 provided a collection of special methods that show the flexibility and usefulness of pandas. This chapter has been like an illustrated glossary in which each function serves a very unique purpose. Now, you should have an idea of how to create and apply one-liner functions in pandas, and you should understand the concepts of missing values and the methods that take care of them. This is also a compendium of all the miscellaneous methods that can be applied to a series and the numeric methods that can be applied to any kind of Python data structure.

In the next chapter, we will take a look at how we can handle time series data and plot it using matplotlib. We will also have a look into the manipulation of time series data by looking at rolling, resampling, shifting, lagging, and time element separation.
