You are getting bogged down with implementation details; not even dict, list, nor tuple actually have the contained
objects inside their memory space. What they have is a record of what objects they "contain", and methods to work with
those objects.
Whether a "contained" object exists before it is accessed is irrelevant, is an implementation detail, and is a level of
optimization.
