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.

Chapter 7: Financial Analysis – Bitcoin and the Stock Market

It's time to switch gears and work on an application. In this chapter, we will explore a financial application by performing an analysis of bitcoin and the stock market. This chapter builds upon everything we have learned so far—we will extract data from the Internet; perform some exploratory data analysis; create visualizations with pandas, seaborn, and matplotlib; calculate important metrics for analyzing the performance of financial instruments using pandas; and get a taste of building some models. Note that we are not trying to learn financial analysis here, but rather walk through an introduction of how the skills we have learned in this book can be applied to financial analysis.

This chapter is also a departure from the standard workflow in this book. Up until this point, we have been working with Python as more of a functional programming language. However, Python also supports object-oriented...
