numpy.info(object=None, maxwidth=76, output=<_io.TextIOWrapper name='<stdout>' mode='w' encoding='utf-8'>, toplevel='numpy')[source]¶

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

Parameters

objectobject 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.
maxwidthint, optional: Printing width.
outputfile 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.

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.

>>> np.info('fft') 
     *** Found in numpy ***
Core FFT routines
...
     *** Found in numpy.fft ***
 fft(a, n=None, axis=-1)
...
     *** Repeat reference found in numpy.fft.fftpack ***
     *** Total of 3 references found. ***
