The nearest term I can come up with here is that those three are
*atoms*. They might be implemented as integers (most C-style APIs work
that way), or as strings (which is apparently the case in Tkinter), or
as instances of object() that exist solely so their identities can be
checked (Python function default arguments are often done that way),
but there's only one operation you're allowed to do: Ask if one atom
is identical to another atom.
