Introduction UUID Regex Python

Validating UUIDs in Python is essential in applications where unique identifiers are crucial. Python's re module facilitates regex-based validation. A typical regex pattern for UUID validation is

^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-5][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}$

What is UUID Regex?

The regex pattern for UUIDs ensures the format follows the standard 8-4-4-4-12 character structure.

The UUID Regex Pattern

Pattern: ^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-5][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}$

How to Validate UUIDs in Python?

To validate UUIDs using regex in Python:

import re

def is_valid_uuid(uuid):
    uuid_regex = re.compile(r'^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-5][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}$')
    return bool(uuid_regex.match(uuid))

test_uuid = "123e4567-e89b-12d3-a456-426655440000"
print(f"Is '{test_uuid}' a valid UUID? {is_valid_uuid(test_uuid)}")

Uses of UUID Regex Validation

1. Unique Identifier Verification: Ensuring the correctness of UUIDs in database transactions and data exchange.

2. Data Integrity: Maintaining the standard structure of UUIDs in system logs, configuration files, and APIs.

What next?

Python's regex capabilities make it straightforward to validate UUIDs, ensuring they adhere to the standard format. Akto's regex validator can provide additional validation support, especially for complex or non-standard UUID formats.
