1. Abstract

The namedtupledefs package provides a patched version of the original collections.namedtuple. The namedtupledefs package introduces:

• field defaults

  Default values for the fields in function style see [PYFUNC] The implementation is pure dynamic by generated default values for the method __new__, thus has no impact on the created namedtuple class. Neither on resources, nor on performance. See API_NEW.

• merge

  In addition the method _merge is added to the created named tuple class. This provides the concatination of multiple results from namedtuple into a new instance of a new class. See API_MERGE, Python2, and Python3.
