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()
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

If youre 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)

>>> import uuid

>>> # make a UUID based on the host ID and current time
>>> uuid.uuid1()
UUID(a8098c1a-f86e-11da-bd1a-00112444be1e)

>>> # make a UUID using an MD5 hash of a namespace UUID and a name
>>> uuid.uuid3(uuid.NAMESPACE_DNS, python.org)
UUID(6fa459ea-ee8a-3ca4-894e-db77e160355e)

>>> # make a random UUID
>>> uuid.uuid4()
UUID(16fd2706-8baf-433b-82eb-8c7fada847da)

>>> # make a UUID using a SHA-1 hash of a namespace UUID and a name
>>> uuid.uuid5(uuid.NAMESPACE_DNS, python.org)
UUID(886313e1-3b8a-5372-9b90-0c9aee199e5d)

>>> # make a UUID from a string of hex digits (braces and hyphens ignored)
>>> x = uuid.UUID({00010203-0405-0607-0809-0a0b0c0d0e0f})

>>> # convert a UUID to a string of hex digits in standard form
>>> str(x)
00010203-0405-0607-0809-0a0b0c0d0e0f

>>> # get the raw 16 bytes of the UUID
>>> x.bytes
x00x01x02x03x04x05x06x07x08tnx0bx0crx0ex0f

>>> # make a UUID from a 16-byte string
>>> uuid.UUID(bytes=x.bytes)
UUID(00010203-0405-0607-0809-0a0b0c0d0e0f)
