You can't pass the object a subscript (the expression between the square
brackets) and get a meaningful answer.
Being indexable is subtly different from being subscriptable - the
former has stronger connotations of numeric indices and sequence-like
behaviour (particularly since the introduction of operator.index), while
the latter merely states that the container provides some kinds of
mapping from subscripts to values in the container, without provide any
implications as to the nature of that mapping.
'Unsubscriptable' may be a bit clumsy, but it's as accurate a
description of the error as you're likely to find.
Cheers,
Nick.
