In addition to the basic PyQt5 setup that we've used in this book, you will need to make sure you have the PyQtWebEngine package installed from PyPI. You can do this using the following command:
$ pip install --user PyQtWebEngine
You may also want the example code for this chapter, and this is available from https://github.com/PacktPublishing/Mastering-GUI-Programming-with-Python/tree/master/Chapter16.
