Using NumPy's 'random' package (randint and shuffle)

randint
>>> np.random.randint(4)
0
>>> np.random.randint(4)
3
>>> np.random.randint(4)
2
>>> np.random.randint(4)
0

shuffle

>>>arr = np.arange(10)
>>>np.random.shuffle(arr)
>>>arr

[1 7 5 2 9 4 3 6 0 8] # random

>>> import numpy as np
>>> arr = [0, 1, 2, 3]
>>> np.random.shuffle(arr)
>>> arr
[1, 0, 2, 3]
>>> np.random.shuffle(arr)
>>> arr
[0, 1, 3, 2]
