How to create a GUID/UUID in Python

The uuid module provides immutable UUID objects (the UUID class) and the functions uuid1(), uuid3(), uuid4(), uuid5() for generating version 1, 3, 4, and 5 UUIDs as specified in RFC 4122.

If all you want is a unique ID, you should probably call uuid1() or uuid4(). Note that uuid1() may compromise privacy since it creates a UUID containing the computer’s network address. uuid4() creates a random UUID.


Examples (for both Python 2 and 3):

>>> import uuid

>>> # make a random UUID
>>> uuid.uuid4()

>>> # Convert a UUID to a string of hex digits in standard form
>>> str(uuid.uuid4())

>>> # Convert a UUID to a 32-character hexadecimal string
>>> uuid.uuid4().hex
