I refer all sequences, but, as you say, particularly numpy arrays.

Right, we can use scientific binary formats, like NetCDF, HDF.
But, we often want to read the data in our naked eyes
and exchange them with spreadsheet.

Trivial to create my own function.
But, surprisingly no common function or command for the work.
Maybe, one solution is
import Numeric as N
