random number generator python in range code example

Example 1: python how to generate random number in a range

import random

# generates completely random number
x = random.random()

# generates a random int
x = random.randint()

# generates a random int in a range
x = random.randint(1, 100)

# NOTE: RANGE DOESN'T WORK FOR random.random()

Example 2: python list of random values

# To create a list of random integer values:
import random
randomlist = random.sample(range(10, 30), 5)
# Output:
# [16, 19, 13, 18, 15]

# To create a list of random float numbers:
import numpy
random_float_array = numpy.random.uniform(75.5, 125.5, 2)
# Output:
# [107.50697835, 123.84889979]

Example 3: random range python

from random import randrange
print(randrange(10))

Example 4: python random integer in range

import random
print(random.randint(0,9))

Example 5: place a number randomly in a list python

offsetBiasSample = [randint(-10,10)/100 for i in range(10)]
offsetBias = choice(offsetBiasSample)
index_offsetBias = randint(0,len(oldBiases)-1)
oldBiases[index_offsetBias] = oldBiases[index_offsetBias] + offsetBias
