Overview of this book

Extracting valuable business insights is no longer a ‘nice-to-have’, but an essential skill for anyone who handles data in their enterprise. Hands-On Data Analysis with Pandas is here to help beginners and those who are migrating their skills into data science get up to speed in no time. This book will show you how to analyze your data, get started with machine learning, and work effectively with the Python libraries often used for data science, such as pandas, NumPy, matplotlib, seaborn, and scikit-learn. Using real-world datasets, you will learn how to use the pandas library to perform data wrangling to reshape, clean, and aggregate your data. Then, you will learn how to conduct exploratory data analysis by calculating summary statistics and visualizing the data to find patterns. In the concluding chapters, you will explore some applications of anomaly detection, regression, clustering, and classification using scikit-learn to make predictions based on past data. This updated edition will equip you with the skills you need to use pandas 1.x to efficiently perform various data manipulation tasks, reliably reproduce analyses, and visualize your data for effective decision making – valuable knowledge that can be applied across multiple domains.

To get the most out of this book

You should be familiar with Python, particularly Python 3 and up. You should also know how to write functions and basic scripts in Python, understand standard programming concepts such as variables, data types, and control flow (if/else, for/while loops), and be able to use Python as a functional programming language. Some basic knowledge of object-oriented programming may be helpful but is not necessary. If your Python prowess isn't yet at this level, the Python documentation includes a helpful tutorial for quickly getting up to speed:

The accompanying code for this book can be found on GitHub at To get the most out of this book, you should follow along in the Jupyter Notebooks as you read through each chapter. We will cover setting up your environment and obtaining these files in Chapter 1, Introduction to Data Analysis. Note that there is also a Python 101 notebook that provides a crash course/refresher, if needed:

Lastly, be sure to do the exercises at the end of each chapter. Some of them may be quite challenging, but they will make you much stronger with the material. Solutions for each chapter's exercises can be found at in their respective folders.
