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.

<code>randint(range1, range2)</code>

Import the module and generate a four‑digit number by setting the range from 1000 to 9999.

<code>import random
randomNumber = random.randint(1000, 9999)
print(randomNumber)</code>

Sample output:

Using random.randrange() method

The

randrange()

function works similarly to

randint()

, requiring a start and end value.

<code>randrange(range1, range2)</code>

Example code:

<code>import random
randomNumber = random.randrange(1000, 9999)
print(randomNumber)</code>

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()

.

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

Full example:

numbers = string.digits
randomNumber = ''.join(choice(numbers) for _ in range(4))
print(randomNumber)</code>

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.
