This is about *Alice*, not about Python, the programming language.
Is this the same Alice tutorial that comes with Alice when you download it?
There's not a single line of Python in that. There *are* Python names
in there, but not a line of Python code, as far as I recall.

This would indicate that they were writing Python code later. Note the

"Coming to terms with indentation is a difficult skill for many to learn,.."
"Coming to terms with variables.."
"Coming to terms with mutable versus immutable variables.."
There are a lot of things that we could do to make Python easier to
learn for newbies. Let the editor mark names that refer to
immutable objects in a special color. I think case insensitivity
is insignificant to what you can do with a decent IDE, except that
it trips up half of the experienced programmers. :)

No, WWW -- Could we be going in the right direction?
