Why this code behaves abnormally when using numpy?

Question

So in this code I used the randint function from the built-in random module. But when I use the randint function from numpy's random module it shows some unexpected results. Why does this happen? You can try this by changing the first line with:

from numpy.random import randint

Answer 1

random.randint(a, b) returns a number with the upper bound inclusive
(a <= x <= b)

numpy.random.randint(a, b) returns a number with upper bound exclusive
(a <= x < b)

It's not abnormal, they are just different.

Tibor Santa Hm.. That's what I was thinking. Thanks for the confirmation. 😄
