# list_functions¶

sherpa.astro.ui.list_functions(outfile=None, clobber=False)

Display the functions provided by Sherpa.

Unlike the other list_xxx commands, this does not return an array. Instead it acts like the show_xxx family of commands.

Parameters
• outfile (str, optional) – If not given the results are displayed to the screen, otherwise it is taken to be the name of the file to write the results to.

• clobber (bool, optional) – If outfile is not None, then this flag controls whether an existing file can be overwritten (True) or if it raises an exception (False, the default setting).

Raises

sherpa.utils.err.IOErr – If outfile already exists and clobber is False.
