[AstroPy] Write machine readable tables in Python?

[Kevin Gullikson]

Leo,

As far as implementing a writer in Astropy, the trickiest part would be
writing the Fortran-style format strings. Probably the most reliable method
would be to write the table data using the existing fixed-width formatter,
then read it back to deduce the format string.

I have used the fortranformat
<https://pypi.python.org/pypi/fortranformat>package for fortran-format
strings in the past. I've found that the string
formatting in python has a really hard time getting everything right for
input to fortran programs.
