Random Module

The random module in Python provides functions for generating random numbers.

Task

Generate a 32-character password that contains random lowercase and uppercase letters, as well as numbers.

JavaScript implementation

function generatePassword() {
  var length = 32;
  var charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
  var password = "";
  
  for (var i = 0; i < length; i++) {
    var randomIndex = Math.floor(Math.random() * charset.length);
    password += charset.charAt(randomIndex);
  }
  
  return password;
}

var password = generatePassword();
console.log(password);

Python implementation

import random
import string

def generate_password():
    length = 32
    charset = string.ascii_letters + string.digits
    password = ''.join(random.choice(charset) for _ in range(length))
    return password

password = generate_password()
print(password)

Code Highlight

• The string module in Python contains ascii_letters which includes all lowercase and uppercase letters, and digits which includes all digits.
• In Python, random.randint() function is used to generate a random integer between the given minimum and maximum values. In JavaScript, we use a custom function getRandomInt() with Math.random() to achieve the same functionality.

Difference Quick View

Feature	JavaScript	Python
Generate a random number between 0 and 1	Math.random()	random.random()
Generate a random integer within a range	Math.floor(Math.random() * (max - min + 1)) + min	random.randint(min_val, max_val)
Choose a random element from a list	-	random.choice(sequence)
Shuffle the elements in a list	-	random.shuffle(sequence)
Generate a random float within a range	-	random.uniform(min_val, max_val)
Set a random seed	-	random.seed(seed_val)
