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.

Docs:

Examples (for both Python 2 and 3):

>>> import uuid>>> # make a random UUID>>> uuid.uuid4()UUID('bd65600d-8669-4903-8a14-af88203add38')>>> # Convert a UUID to a string of hex digits in standard form>>> str(uuid.uuid4())'f50ec0b7-f960-400d-91f0-c42a6d44e3d0'>>> # Convert a UUID to a 32-character hexadecimal string>>> uuid.uuid4().hex'9fe2c4e93f654fdbb24c02b15259716c'


If you're using Python 2.5 or later, the uuid module is already included with the Python standard distribution.

Ex:

>>> import uuid>>> uuid.uuid4()UUID('5361a11b-615c-42bf-9bdb-e2c3790ada14')
