numpy.random.randint code example

Example 1: 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'

Example 2: python randint

from random import randint

# generate an integer between 3 and 9 (inclusive range).
# (see randrange for exclusive range)
print(randint(3, 9))

Example 3: python randint

from random import randint

print(randint(3, 9))

Example 4: numpy randint

>>> np.random.randint(2, size=10)
array([1, 0, 0, 0, 1, 1, 0, 0, 1, 0]) # random
>>> np.random.randint(1, size=10)
array([0, 0, 0, 0, 0, 0, 0, 0, 0, 0])

Example 5: 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]])

Example 6: python randint

from random import randint
print(randint(1,2))
