# numpy.info

`numpy.``info`(object=None, maxwidth=76, output=<open file '<stdout>', mode 'w'>, toplevel='numpy')

  Get help information for a function, class, or module.

  Parameters: | object : object or str, optional Input object or name to get information about. If `object` is a numpy object, its docstring is given. If it is a string, available modules are searched for matching objects. If None, information about `info` itself is returned. maxwidth : int, optional Printing width. output : file like object, optional File like object that the output is written to, default is `stdout`. The object has to be opened in ‘w’ or ‘a’ mode. toplevel : str, optional Start search at this level.

  Notes

  When used interactively with an object, `np.info(obj)` is equivalent to `help(obj)` on the Python prompt or `obj?` on the IPython prompt.

  Examples

      >>> np.info(np.polyval)
         polyval(p, x)
           Evaluate the polynomial p at x.
           ...

  When using a string for `object` it is possible to get multiple results.
