create a random numpy array python 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: numpy generate random 2d array
import numpy as np
a=np.random.rand(3,3)
print(a)
