InNamedTuplesubclasses allsuper().__repr__()calls would resolve totuple.__repr__(). This introduces no breaking changes, is additive only and retains the stable behavior of default__repr__of named tuples. With proper documentation, it can hint advanced named tuple users in how to create ...
Add a new function to DataFrames,iterdicts, that takes anindexargument (equivalent to the same argument initertuples) and returns each row as a dictionary the same way itertuples does so as a namedtuple. (No need to take a "name" argument, since that's irrelevant for dictionaries.) ...
