Built-in Modules

Time module

Using time.time() to count how long something takes

import time

start = time.time()

for i in range(10000):
    continue

new_time = time.time()
total_time = new_time - start
print(total_time)

Using time.sleep(n) to wait for n seconds

import time

start = time.time()

time.sleep(10)

end = time.time()

print(start - end)

Random Module

Generate a random number between 0 and 1

import random

num = random.random()
print("the random number is {}".format(num))

Generate a random number between two integers

import random

num = random.randint(5, 100)
print("the random integer between 5 and 100 is {}".format(num))

Select a random item from a list

import random

my_pets = ['euclid', 'leta']
fav_pet = random.choice(my_pets)
print("My randomly chosen favorite pet is {}".format(fav_pet))
