[issue14384] Add "default" kw argument to operator.itemgetter and operator.attrgetter

Raymond Hettinger added the comment: Here are a few more thoughts and a concrete example for clarity. Itemgetter/Attrgetter were designed to make multiple lookups (possibly multi-level) and to return a tuple that need not be homogenous. A single default value

Raymond Hettinger added the comment: FWIW, Joe Jevnik worked hard to squeeze every possible nanosecond out of these calls because they were frequently used. Extending this API will tend to undo his efforts. The original intent of itemgetter() was to provide a

[issue14384] Add default kw argument to operator.itemgetter and operator.attrgetter
