Answers for "np.random.randint python"

generate random integer matrix python

import numpy as np

randi_arr = np.random.randint(start, end, dimensions)
#random integers will be sampled from [start, end) (end not inclusive)
#end is optional; if end is not specified, random integers will be sampled from [0, start) (start not inclusive)
#dimensions can be specified as shown here; (m,n) #2D array with size 'm x n'

np.rand.randint

np.random.randint(0,10, size=(5, 5)) # random integers from 0 to 10 in size 5,5
#o/p 
array([[3, 9, 2, 3, 5],
       [2, 8, 7, 7, 1],
       [8, 2, 1, 1, 9],
       [9, 0, 5, 6, 4],
       [1, 6, 6, 4, 6]])

np.random.randn()

>>> 2.5 * np.random.randn(2, 4) + 3
array([[-4.49401501,  4.00950034, -1.81814867,  7.29718677],  #random
       [ 0.39924804,  4.68456316,  4.99394529,  4.84057254]]) #random

random.randint(0,20) + pyrthon

random.randint(0,20)
