There are about two dozen datasets that are used throughout this book. It can be very helpful to have background information on each dataset as you complete the steps in the recipes. A detailed description of each dataset may be found in the dataset_descriptions Jupyter Notebook found at https://github.com/PacktPublishing/Pandas-Cookbook. For each datastet, there will be a list of the columns, information about each column and notes on how the data was procured.
