Looks to me like you have to do two things to get PyGame Zero going on
Windows.  First, install the latest stable Python 3 from python.org.  Be
sure to tell the installer to put Python in the system path so you can
get to it from the command prompt.

Second, from a command prompt, run:

py -m pip install pgzero

And then you must put the location pgzrun.exe in your path.  See below.

For example this is what you'd see:
C:\Users\torriem>py -m pip install pgzero

WARNING: You are using pip version 19.2.3, however version 20.3.1 is

You should consider upgrading via the 'python -m pip install --upgrade
pip' command.

Note the WARNINGs about the scripts and path. You'll want to take that
directory (which will be different on your machine) and add that to the
path.  See
https://www.architectryan.com/2018/03/17/add-to-the-path-on-windows-10/
for an example of how to do that.

In my case, the path I need to add is
C:\Users\torriem\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\Scripts

After that, pgzrun should run as the book says it will.
