`numpy:info`

Signature

   def     info (    object    =  None   ,    maxwidth    =  76   ,    output    =  None   ,    toplevel    =  numpy     )

Get help information for an array, function, class, or module.

object : object or str, optional: Input object or name to get information about. If object is an ndarray instance, information about the array is printed. 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 None, in which case sys.stdout will be used. The object has to be opened in 'w' or 'a' mode.
toplevel : str, optional: Start search at this level.

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

When using a string for `object` it is possible to get multiple results. When the argument is an array, information about the array is printed.

a = np.array([[1 + 2j, 3, -4], [-5j, 6, 0]], dtype=np.complex64)
