To get the most out of this book

The Python code proposed in this book has been designed to run on a Kaggle Notebook without any installation on a local computer. Therefore, don’t worry about what machine you have available and about what version of Python package you have to install. All you need is a computer with access to the internet and a free Kaggle account. (you will find instructions about the procedures in Chapter 3 of The Kaggle Book). If you don’t have a free Kaggle account yet, just go to www.kaggle.com and follow the instructions on the website.

When referred to a link, just explore it: you can find code available on public Kaggle Notebooks that you can reuse or further materials to illustrate concepts and ideas that we outlined in the book.
