Percentage chance to make action

import random
if random.randint(0,100) < 36:
    do_stuff()

Just to make it more explicitly clear and more readable:

def probably(chance):
    return random.random() < chance

if probably(35 / 100):
    do_the_thing()

You could use random.random:

import random

if random.random() < percentage_chance:
    print('aaa')

This code returns a 1, 36% of the time

import random
import math
chance = 0.36
math.floor( random.uniform(0, 1/(1-chance)) )
