Advance functions for Random number generation in Python

               Random Number generation can be categoried into three categories. Part1 describes the basic type. Part2 deals with the probability distributions. Part3 covers the advanced Random number Generation.

To read the part1,part2,just follow the link.

Advanced methods are given below…

1. ·       Random State / Seed
2. ·       Cryptographically Secure Randoms

1.Random State/Seed:

              It uses ‘seed()’ method. This helps to initialize the generator. As a default value,it seeds the current system time.

First method uses randint() function to print random value.

Second method uses seed() method.

Python code:

import random

# Without seed: different results each run

print("Without seed:")

for _ in range(2):

    print(random.randint(1, 8))

# With seed: same results every run

random.seed(42)

print("\nWith seed (40):")

for _ in range(2):

    print(random.randint(1, 8))

Output:

Without seed:

6

8

With seed (40):

2

1

Next advance method covers the secret key generations.

Cryptographically Secure Randoms:

              It has some built-in modules for generate secret values like passwords and tokens.

Built-in package: secrets

Let us write the python code as follows.

First, import the secrets module and string.

This program covers 6 different methods to generate secret values.

First, it generates random integer within the range given.

Second method creates random integer in 32 bits of size.

Third develops a string randomly from the given list.

Fourth generates a random token in hexadecimal.

Fifth method secretly creates URL value.

Finally, it creates a random password with the combination of strings, integers and ascii values.

Python Code:

import secrets

import string

def secure_random_eg():

    try:

        # 1. let us Secure random integer within the range

        rand_int = secrets.randbelow(50)

        print(f"Secure random integer (0-50): {rand_int}")

        # 2. Secure random integer between two numbers

        rand_range = secrets.randbits(32)           

        print(f"Secure 32-bit random number: {rand_range}")

        # 3. Secure random string in a list

        vehicles = ['audi', 'bmw', 'maruthi','honda','tesla']

        rand_choice = secrets.choice(vehicles)

        print(f"Secure random choice: {rand_choice}")

        # 4. Secure random token in hexadecimal

        token_hex = secrets.token_hex(16) 

        print(f"Secure random hex token: {token_hex}")

        # 5. let us create random token for URL

        token_url = secrets.token_urlsafe(16) 

        print(f"Secure random URL-safe token: {token_url}")

        # 6. random password generator

        sample = string.punctuation + string.digits + string.ascii_letters

        password = ''.join(secrets.choice(sample) for _ in range(12))

        print(f"Secure random password: {password}")

    except Exception as e:

        print(f"Error generating secure randoms: {e}")

if __name__ == "__main__":

    secure_random_eg()

Output:

Secure random integer (0-50): 22

Secure 32-bit random number: 164742466

Secure random choice: audi

Secure random hex token: 83600591f6ec5c62e9aafac09b06653c

Secure random URL-safe token: H8880pWsUXSTMgMyKqBLIw

Secure random password: F4}V|vQ%_#M_

These are the various methods to generate random numbers in advance manner. Hope, this code is useful to you. Keep Coding!!!
