How to Generate Random Four‑Digit Numbers in Python with random.randint and More

Python provides the built‑in random module for generating random numbers, which can be useful for passwords, security pins, and other applications requiring numbers of specific length.

Using random.randint() Method

The randint(start, end) function returns an integer between the given start and end values, inclusive.

import random
randomNumber = random.randint(1000, 9999)
print(randomNumber)

Running this code prints a random four‑digit number each time.

Using random.randrange() Method

The randrange(start, end) function works similarly to randint, returning a random integer from start (inclusive) to end (exclusive).

import random
randomNumber = random.randrange(1000, 9999)
print(randomNumber)

Each execution also yields a random four‑digit number.

Other Ways to Generate Random Numbers in Python

Beyond randint and randrange, you can combine the string module, random.choice, and a for loop to build a random four‑digit string.

from random import choice
import string
numbers = string.digits
randomNumber = ''.join(choice(numbers) for _ in range(4))
print(randomNumber)

Summary

This article introduced Python's random module and demonstrated how to generate random four‑digit numbers using randint, randrange, and a combination of string.digits, choice, and join. While list comprehensions and loops are possible, randint and randrange remain the simplest approaches.
