How to Generate Random 4‑Digit Numbers in Python with randint, randrange, and More

Python provides the built‑in random module for generating random numbers, offering functions such as seed(), randrange(), randint(), choice(), choices(), and shuffle().

Using random.randint() method

The randint() function returns a random integer within a specified inclusive range. randint(range1, range2) Import the module and generate a four‑digit number by setting the range from 1000 to 9999.

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

Sample output:

Using random.randrange() method

The randrange() function works similarly to randint(), requiring a start and end value. randrange(range1, range2) Example code:

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

Sample output:

Other methods to generate random numbers in Python

Beyond randint() and randrange(), you can create a random four‑digit string using string.digits, choice(), and join().

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

Summary

The article introduced Python's random module and demonstrated how to generate a random four‑digit number using randint() and randrange(). It also covered an alternative approach employing string.digits, choice(), and join(). While list comprehensions and loops can create such numbers, randint() and randrange() remain the simplest solutions.
