Return a tuple containing a function which converts a list into a numpy array and the type produced by the converter function.

numpy_typenumpy data-type

The numpy type required of an array returned by converter. Must be a valid numpy type (e.g., numpy.uint, numpy.int8, numpy.int64, numpy.float64) or a python type covered by a numpy type (e.g., int, float, str, bool).

(converter, converter_type)(function, generic data-type)

converter is a function which accepts a list and converts it to a numpy array of type numpy_type. converter_type tracks the generic data type produced by the converter function.
