Fungsi "random()" menghasilkan angka diantara 0 dan 1, seperti [0, 0.1 .... 1].

Generating a random float antara 0 dan 1

from random import random

print(random())

output: 0.332587482267

Angka integer antara 1 dan 100

from random import randint

print(randint(1, 100))

Output : 55

Storing Integer di variabel

from random import randint

number = randint(1, 100)

print(number)

Output: 26

Angka Random Float antara 1 dan 10

Kita bisa memakai Fungsi "uniform()"

from random import uniform

print(uniform(1, 10))

Output : 9.7811

Manipulasi Lists dengan Randomness

from random import shuffle

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

shuffle(numbers)

print(numbers)

Output: [5, 1, 4, 10, 7, 9, 6, 3, 8, 2]

Menyeleksi Hal Random dari List

from random import sample

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

single_item = sample(numbers, 1)[0]

print(single_item)

Output: 8

multiple_items = sample(numbers, 4)

print(multiple_items)

[7, 5, 10, 4]

Lists mengandung Strings

from random import sample

names = ['Alissa', 'Alice', 'Marco', 'Melissa', 'Sandra', 'Steve']

single_name = sample(names, 1)[0]  # Picks one random name from the list.

print(single_name)

Output: Alissa

multiple_names = sample(names, 4)

print(multiple_names)

Output: ['Alice', 'Marco', 'Steve', 'Melissa']
