You can save them to separate fi
How do you want the output files to be formatted? Binary data? Textual
representation?
This function can do both:

And numpy supports a variety of methods for outputting to files (and
reading data back in):

Here's how I sorted primarily by field 'a' descending and secondarily by
field 'b' ascending:
(Note that 'a' is the second column, 'b' is the first)

('c', 0.03),

I've found combinations of sorting and reversing followed by stable
sorting that work, but there must be a straightforward way to do i
