Python uuid.uuid4() example

Python's standard library includes the uuid module. Use uuid.uuid4() when you need a random UUID object.

Generate a UUID in Python

import uuid

value = uuid.uuid4()
print(value)

Convert Python UUID to string

import uuid

value = str(uuid.uuid4())
print(value)

Validate a UUID string in Python

import uuid

def is_uuid(value: str) -> bool:
    try:
        uuid.UUID(value)
        return True
    except ValueError:
        return False

Common Python UUID mistakes

Do not compare UUID objects and strings without converting one side. Do not strip hyphens unless the receiving system expects the compact 32-character form.
