And this is perfectly symmetrical.  Which is why I find
Python's indexing and slicing more intuitive than any
of its predecessors.

I think the "half open interval" notion mentioned above is
equally useful.  Note that both are related to "real number
thinking" and not "integer thinking": i.e. they are distances
or positions, not "numbers of things".

BTW, I think this is more on-topic for the list --- this is the
way to teach Python indexing: as "distances".

Cheers,
Terry
