Math and Random Module

The math Module

import math

print(math.sqrt(64))          # 8.0
print(math.pow(2, 5))          # 32.0
print(math.floor(4.9))          # 4
print(math.ceil(4.1))            # 5
print(math.factorial(6))          # 720
print(math.pi)                     # 3.141592653589793
print(math.gcd(24, 36))             # 12
print(round(math.sqrt(2), 3))        # 1.414

The random Module

import random

print(random.random())              # e.g. 0.7294...
print(random.randint(1, 100))         # e.g. 42
print(random.randrange(0, 50, 5))      # e.g. 30 (multiple of 5)

colors = ["red", "green", "blue", "yellow"]
print(random.choice(colors))           # e.g. 'blue'
print(random.sample(colors, 2))         # e.g. ['red', 'yellow']

random.shuffle(colors)
print(colors)                           # colors reordered randomly

print(random.uniform(1, 10))             # e.g. 6.732...

Example: Simulate a dice roll

import random

def roll_dice():
    return random.randint(1, 6)

for _ in range(5):
    print(roll_dice())

Example: OTP generator using random

import random

otp = "".join(str(random.randint(0, 9)) for _ in range(6))
print("Your OTP is:", otp)
