Python's list and, I believe, other builtin roster objects do have a
C-level length attribute. For mutables, it is updated. __len__ is just a
get of int value the and conversion to int object. Min and max are defined
and sensible for only a subset of lists, and when they are, are very seldom
need repeated updates.

For the fraction of times used, yes.
