“In order to use a GUI, we need to use an external module to do
all the grunt work behind making the interface components and
presenting them to the end user. There are a number of different
modules which can be used. We are going to use one called
‘Tkinter’. We are going to use Tkinter because it should come as
part of every Python installation, so there’s no additional
downloading to do, nor any need to get the Responsible Adult
involved – but leave a comment if you have problem with
Tkinter.”
