save_arrays

Context: saving

Synopsis

Write a list of arrays to a file.

Syntax

save_arrays(filename, args, fields=None, ascii=True, clobber=False)

Examples

Example 1

Write the x and y columns from the default data set to the file 'src.dat':

>>> x = get_indep()
>>> y = get_dep()
>>> save_arrays('src.dat', [x, y])

Example 2

Use the column names "r" and "surbri" for the columns:

>>> save_arrays('prof.fits', [x,y], fields=["r", "surbri"],
...             ascii=False, clobber=True)

PARAMETERS

The parameters for this function are:

Parameter Type information Definition
filename str The name of the file to write the array to.
args array of arrays The arrays to write out.
fields array of str The column names (should match the size of `args` ).
ascii bool, optional If False then the data is written as a FITS format binary table. The default is True . The exact format of the output file depends on the I/O library in use (Crates or AstroPy).
clobber bool, optional This flag controls whether an existing file can be overwritten ( True ) or if it raises an exception ( False , the default setting).
