Thanks for the replies. All is now well!
I'm thankful that this list is so very patient with ROF's (retired old
fools) struggling to learn a new programmng language.

Hi,
Note that your *data* array is made of strings and not floats.
The default value of the *dtype* argument is *float*, which you
override by *None.*
Remove the 'dtype=None' part to correctly load data
You then have no problem to save your data with the format you want.
Fabrice
PS : be aware that [data] is a 2D row array, that will end up inlined
with command
np.savetxt('13-7', [data], fmt='%15.9f', header='13-7')
Remove the bracket for a one-per-line formatted output
np.savetxt('13-7', data, fmt='%15.9f', header='13-7')
