When used interactively with an object,
np.info(obj)
is equivalent tohelp(obj)
on the Python prompt orobj?
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. ***
