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 materials

For this chapter, we will be creating our own package for stock analysis. This makes it extremely easy for us to distribute our code and for others to use our code. The final product of this package is on GitHub at https://github.com/stefmolin/stock-analysis/tree/2nd_edition. Python's package manager, pip, is capable of installing packages from GitHub and also building them locally; this leaves us with either of the following choices as to how we want to proceed:

  • Install from GitHub if we don't plan on editing the source code for our own use.
  • Fork and clone the repository and then install it on our machine in order to modify the code.

If we wish to install from GitHub directly, we don't need to do anything here since this was installed when we set up our environment back in Chapter 1, Introduction to Data Analysis; however, for reference, we would do the following to install packages from GitHub:

(book_env) $ pip3 install \
