numpy create random array code example

Example 1: random array numpy

>>> np.random.rand(3,2)
array([[ 0.14022471,  0.96360618],  
       [ 0.37601032,  0.25528411],  
       [ 0.49313049,  0.94909878]]) 

>>> np.random.random_integers(low=0, high=9, size=(3,2))
array([[2, 3],
       [2, 3],
       [6, 3]])

Example 2: random matrix python

np.random.rand(3,2)

Example 3: numpy generate random 2d array

import numpy as np
a=np.random.rand(3,3)
print(a)
