I find that when teaching beginning programmers, they usually think in
until terms, and not while terms.
If really beginning, an overview of this whole idea of control structures
makes sense, such as this wikipedia article:

Then explain how Python is

I haven't noticed that so much myself, actually... My students (grades
8-10) tend to think in fixed numbers of repetitions and the whole idea
of a flexible loop is a
they find the while logic to be unintuitive
I've found that a good way to explain 'while' is to consider it as an 'if'
statement that repeats. Kids grasp simple conditionals fairly easily. I
would sometimes hear them talk about 'if loops' when they were actually
trying to discuss conditional
Also people have different styles, like you
don't need to use a bare True, but might
go like:
untouched = True
while untouched:
keepmoving()
or something similar.

Nice wrapper class Kirby!
One thought: multiplying functions is another operation. I would
tend to reserve '*' for that, or you will be confusing of limited.
Since the raised circle is not a python operator, it appears you need
to use a different, nonstandard composition symbol. Perhaps '%' (it

We say another operation but then we deliberately re-confuse them

If Python's main goal was to be the most beginner friendly programming
language for the first x hours, then it should probably provide many
more such constructs; PASCAL FOR-loop is also easier to teach to novices
than
