write

astropy.io.ascii.write(table, output=None, format=None, fast_writer=True, *, overwrite=False, **kwargs)

Write the input table to filename. Most of the default behavior for various parameters is determined by the Writer class.

Help on the write() function arguments is available as shown in this example:

from astropy.io import ascii
ascii.write.help()  # Common help for all formats
ascii.write.help("html")  # Common help plus "html" format-specific args
