Random 4 Digit Number Generator

In this article, we’ll delve into the world of creating random 4 digit number generator using Python. Whether you’re a beginner or an experienced developer, this guide will equip you with the knowledge and tools you need to master this essential skill.

Random 4 Digit Number Generator
  • Random: In programming, randomness refers to generating values that lack a discernible pattern or predictability. Randomness is crucial for diverse applications like simulations, games, and encryption.
  • 4-Digit Number: A 4-digit number is any number that ranges from 1000 to 9999. It contains four digits, allowing for a total of 9000 possible combinations.
  • Generator: A generator is a function or mechanism that produces a sequence of values on-the-fly. In our context, it’s about creating random numbers efficiently.
  • Python: Python is a widely-used programming language known for its simplicity and versatility. It offers built-in functions and libraries that make tasks like random number generation straightforward.

Here’s a step-by-step guide on how to generate random 4-digit numbers in Python using the random module.

Import the random module: Begin by importing the random module, which offers functions for generating random numbers.

Generate the 4-digit number

Utilize the randrange() function to generate a random number within a specified range.

four_digit_number = random.randrange(1000, 10000)

Print the result

Finally, print the generated random 4-digit number.

print("Random 4-digit number:", four_digit_number)

Generating Random 4-Digit Numbers in JavaScript:

To generate random 4-digit numbers in JavaScript, you can use the following steps:


JavaScript provides the Math.random() function, which returns a random floating-point number between 0 (inclusive) and 1 (exclusive). To create a 4-digit number, you can use the following code:

const random4DigitNumber = Math.floor(Math.random() * 9000) + 1000;

Adding Data in Table Form

Here’s a comparison table highlighting the pros and cons of each language’s approach:

JavaScriptMath.random()– Simple and built-in– Limited control over randomness
JavaScriptExternal Libraries– Enhanced features– May require additional dependencies
Pythonrandom.randint()– Straightforward and built-in– Limited cryptographic strength
Pythonsecrets module– More secure for sensitive applications– Requires Python 3.6 or later

Benefits of Random 4-Digit Number Generators

  • Data Encryption and Security: Secure communication and data encryption often require random values. Random 4-digit numbers can be used to create encryption keys and tokens, enhancing the overall security of sensitive information.
  • Password Generation: Generating strong, unpredictable passwords is essential to prevent unauthorized access. By using random 4-digit number generators, users can create complex and unique passwords.
  • Gaming and Simulations: Video games and simulations frequently rely on random events. From dice rolls to card draws, random 4-digit numbers can add an element of chance and excitement to these experiences.
  • Data Masking: In scenarios where real data needs to be masked or anonymized for testing purposes, random 4-digit numbers can replace sensitive information effectively.

Implementation in Java

To implement a random 4-digit number generator in Java, you can use this code.

import java.util.Random;

public class FourDigitRandomGenerator {
    public static void main(String[] args) {
        Random random = new Random();

        int min = 1000; // Minimum 4-digit number

        int max = 9999; // Maximum 4-digit number

        int random4DigitNumber = random.nextInt(max - min + 1) + min;
        System.out.println("Random 4-Digit Number: " + random4DigitNumber);
