Your format string will need 5 different format specifiers if F has 5 columns.

>>> savetxt('f06.dat', F, fmt='%10.5f %4d %10.5f %10.5f %10.5f')

The above should work with your (m, 5) array, giving you an integer in
the second column of each line in the file, with all other columns
being floating point.

The documentation for savetxt is at
