Overview

The numpy.random module supplements the built-in Python random module with functions for efficiently generating whole arrays of sample values from many kinds of probability distributions.

np.random.standard_normal(10)

array([-0.31574999, -0.22620981,  0.78084923, -0.08299547,  0.02537403, -0.39786547,  0.69732466, -1.76220064,  0.26101635, -0.32073839])

np.random.standard_normal(size=(5, 3))

array([[ 6.26367775e-01, -7.97741988e-01,  1.53270456e-01],
       [ 1.66227193e+00, -1.16015757e-03,  9.65301493e-01],
