How to use the numpy generate a random matrix

The results:

[[ 6  7  8  9 10 11]
 [12 13 14 15 16 17]
 [30 31 32 33 34 35]
 [18 19 20 21 22 23]
 [24 25 26 27 28 29]
 [ 0  1  2  3  4  5]]

The codes:

import numpy as np
arr = np.arange(36).reshape((6, 6))
np.random.shuffle(arr)
print(arr)

Generate a uniform random number range from [0,1]

array([0, 0, 1, 0, 1, 0, 1, 0, 1, 1])

The codes:

np.random.randint(0,1+1,10) 

reference:

numpy.random.random_integers — NumPy v1.21 Manual

The results:

[31, 34, 35, 30, 32, 33]

The codes:

a = [30, 31, 32, 33, 34, 35]
np.random.shuffle(a)
print(a)
