Re: scope of function parameters

Python works in terms of objects having names, and one

Or no names. So it's less accurate (though better than talking of
“variables”) to speak of Python objects “having names”.

The names b and c aren't boxes that hold things, they are -- in the
words of one of this group's old hands -- sticky-note labels that have
been slapped on the same object.

Right. And in that analogy, the object *still* doesn't “have a name”
(since that implies the false conclusion that the object knows its own
name); rather, the name is bound to the object, and the object is
oblivious of this.

I prefer to talk not of sticky notes, but paper tags with string; the
string leading from tag to object is an important part, and the paper
tag might not even have a name written on it, allowing the same analogy
to work for other non-name references like list indices etc.
