I prefer namedtuples or dataclasses over tuples. They allow you to refer 
to their fields by name instead of index: student.gpa is much clearer 
than student[2], and makes it less likely to accidentally refer to the 
wrong field.

he had achieved so much — the wheel, New York, wars and so on — whilst all
the dolphins had ever done was muck about in the water having a good time.
But conversely, the dolphins had always believed that they were far more
intelligent than man — for precisely the same reasons."
