Python Random number

Numpy Random number

Use Numpy random to generate random number easily

This is simple an example.

import numpy.random as random
import numpy as np

# 10 random number  Average : 0, Var: 1
rdn_data = random.randn(10)
print('10 randoms:', rnd_data)

rand vs randn

rand : 0 – 1 Uniform Distribution

randn : – 1 – 1 Gaussian Distribution

X to Y random number

Try to set range from X to Y (N random number)

N = 10
Y = 30
X = 50
rand(N) * Y + X

Time seed

To make random number, we need to set seed (to generate actual random)

import numpy.random as random
import numpy as np
import time

random.seed(int(time.time()))
