Overview of this book

Hands-On Data Preprocessing is a primer on the best data cleaning and preprocessing techniques, written by an expert who’s developed college-level courses on data preprocessing and related subjects. With this book, you’ll be equipped with the optimum data preprocessing techniques from multiple perspectives, ensuring that you get the best possible insights from your data. You'll learn about different technical and analytical aspects of data preprocessing – data collection, data cleaning, data integration, data reduction, and data transformation – and get to grips with implementing them using the open source Python programming environment. The hands-on examples and easy-to-follow chapters will help you gain a comprehensive articulation of data preprocessing, its whys and hows, and identify opportunities where data analytics could lead to more effective decision making. As you progress through the chapters, you’ll also understand the role of data management systems and technologies for effective analytics and how to use APIs to pull data. By the end of this Python data preprocessing book, you'll be able to use Python to read, manipulate, and analyze data; perform data cleaning, integration, reduction, and transformation techniques, and handle outliers or missing values to effectively prepare data for analytic tools.

Chapter 1: Review of the Core Modules of NumPy and Pandas

NumPy and Pandas modules are capable of meeting your needs for the majority of data analytics and data preprocessing tasks. Before we start reviewing these two valuable modules, I would like to let you know that this chapter is not meant to be a comprehensive teaching guide to these modules, but rather a collection of concepts, functions, and examples that will be invaluable, as we will cover data analytics and data preprocessing in proceeding chapters.

In this chapter, we will first review the Jupyter Notebooks and their capability as an excellent coding User Interface (UI). Next, we will review the most relevant data analytic resources of the NumPy and Pandas Python modules.

The following topics will be covered in this chapter:

  • Overview of the Jupyter Notebook
  • Are we analyzing data via computer programming?
  • Overview of the basic functions of NumPy
  • Overview of Pandas
