   You say it's "sample code". One possibility is that
sample code is not supposed to do what it does in the
best possible way, it's supposed to do what it does in
the most _illustrative_ possible way - it's supposed to
be a sample of how to do things in other situations
where the class will have more interesting methods.

   (Another possibility is that you overlooked the fact
that the class in question derives from another class,
so it actually does include more than just __init__,
you just don't see it on that page.)
