To shift distribution use the loc parameter. instances methods are imported into the numpy.random namespace, see than the optimized sampler even if each element of p is 1 / len(a). For instance: #This is equivalent to np.random.randint(0,5,3), #This is equivalent to np.random.permutation(np.arange(5))[:3], array(['pooh', 'pooh', 'pooh', 'Christopher', 'piglet'], # random, Mathematical functions with automatic domain. You won't be able directly with np.random.randint, since it doesn't offer the possibility to randomly sample without replacement. For now, I am drawing each sample individually inside of a for-loop using np.random.permutation(N)[0:k], but I am interested to know if there is a more "numpy-esque" way which avoids the use of a for-loop, in analogy to np.random.rand(M) vs. for i in .
