Sorry, I don't understand the question. The difference
for my use is that a np.RandomState instance provides
access to a different set of methods, which unfortunately
does not include an equivalent to random.Random's sample
method but which does include others I need.
Would it be appropriate to request that an analog
to random.sample be added to numpy.random?
(It might sample only a range, since producing indexes
would provide the base functionality.)
Or is this functionality absent intentionally?
