Figure 1.1: Upgrading packages
To get started with Python 3 on a Chromebook, click the time in the lowerright
corner. If you have the appropriate permissions on the Chromebook, you
should see a Settings button that looks like a flower with a dot in the middle
of it. Once you are in Settings, you can scroll down until you find Linux (Beta)
and then enable it by clicking Turn On. It may take several minutes, but once
it is complete, you will be able to run Linux tools, editors, and IDEs on your
Chromebook. To continue with the Chromebook installation, see the next section
for instructions on how to install NumPy and Matplotlib.
Installing Additional Packages
Many of the coding recipes that you will find in this book require additional
packages or modules to help reduce the amount of code you need to write to
ensure message security. Most Python interpreters use a command-line approach
of loading the packages. Integrated development environments (IDEs) may have
unique ways of loading packages for each interpreter available.
