uuid Library

UUID generation library, matching Python’s uuid module.

Import

import uuid

Available Functions

Functions

uuid1()

Generate a UUID version 1 (time-based).

Based on current time and MAC address. Good for generating unique IDs where time ordering matters.

id = uuid.uuid1()
print(id)  # e.g., "f47ac10b-58cc-1e4c-a26f-e3fc32165abc"

uuid4()

Generate a UUID version 4 (random).

Randomly generated UUID. Most commonly used for general-purpose unique identifiers.

id = uuid.uuid4()
print(id)  # e.g., "550e8400-e29b-41d4-a716-446655440000"

uuid7()

Generate a UUID version 7 (Unix timestamp-based, sortable).

Based on Unix timestamp in milliseconds. UUIDs generated in sequence will sort in chronological order. Ideal for database primary keys.

id = uuid.uuid7()
print(id)  # e.g., "018f6b1c-4e5d-7abc-8def-0123456789ab"

Examples

Generate Unique Request ID

import uuid

def make_request():
    request_id = uuid.uuid4()
    print("Request ID:", request_id)
    # Use request_id for tracking...

make_request()

Database Record ID

import uuid

def create_record(data):
    record = {
        "id": uuid.uuid7(),  # Sortable by creation time
        "data": data
    }
    return record

record = create_record({"name": "Test"})
print(record["id"])

Batch Processing with Ordered IDs

import uuid
import time

ids = []
for i in range(3):
    ids.append(uuid.uuid7())
    time.sleep(0.01)  # Small delay

# IDs will be in chronological order
for id in ids:
    print(id)

Python Compatibility

• uuid1() - ✅ Compatible
• uuid4() - ✅ Compatible
• uuid7() - ✅ Compatible (Python 3.12+)

Note: Python’s uuid module also provides uuid3() and uuid5() (name-based) which are not currently implemented.
