1 :mod:`uuid` --- UUID objects according to RFC 4122
5    :synopsis: UUID objects (universally unique identifiers) according to RFC 4122
13 This module provides immutable :class:`UUID` objects (the :class:`UUID` class)
19 a UUID containing the computer's network address.  :func:`uuid4` creates a
20 random UUID.
23 .. class:: UUID(hex=None, bytes=None, bytes_le=None, fields=None, int=None, version=None)
25    Create a UUID from either a string of 32 hexadecimal digits, a string of 16
32    expressions all yield the same UUID::
34       UUID('{12345678-1234-5678-1234-567812345678}')
35       UUID('12345678123456781234567812345678')
36       UUID('urn:uuid:12345678-1234-5678-1234-567812345678')
37       UUID(bytes=b'\x12\x34\x56\x78'*4)
38       UUID(bytes_le=b'\x78\x56\x34\x12\x34\x12\x78\x56' +
40       UUID(fields=(0x12345678, 0x1234, 0x5678, 0x12, 0x34, 0x567812345678))
41       UUID(int=0x12345678123456781234567812345678)
44    The *version* argument is optional; if given, the resulting UUID will have its
48    Comparison of UUID objects are made by way of comparing their
49    :attr:`UUID.int` attributes.  Comparison with a non-UUID object
54    represent the UUID.
56 :class:`UUID` instances have these read-only attributes:
58 .. attribute:: UUID.bytes
60    The UUID as a 16-byte string (containing the six integer fields in big-endian
64 .. attribute:: UUID.bytes_le
66    The UUID as a 16-byte string (with *time_low*, *time_mid*, and *time_hi_version*
70 .. attribute:: UUID.fields
72    A tuple of the six integer fields of the UUID, which are also available as six
78    | :attr:`time_low`             | the first 32 bits of the UUID |
80    | :attr:`time_mid`             | the next 16 bits of the UUID  |
82    | :attr:`time_hi_version`      | the next 16 bits of the UUID  |
84    | :attr:`clock_seq_hi_variant` | the next 8 bits of the UUID   |
86    | :attr:`clock_seq_low`        | the next 8 bits of the UUID   |
88    | :attr:`node`                 | the last 48 bits of the UUID  |
96 .. attribute:: UUID.hex
98    The UUID as a 32-character hexadecimal string.
101 .. attribute:: UUID.int
103    The UUID as a 128-bit integer.
106 .. attribute:: UUID.urn
108    The UUID as a URN as specified in RFC 4122.
111 .. attribute:: UUID.variant
113    The UUID variant, which determines the internal layout of the UUID. This will be
118 .. attribute:: UUID.version
120    The UUID version number (1 through 5, meaningful only when the variant is

150    Generate a UUID based on the MD5 hash of a namespace identifier (which is a
151    UUID) and a name (which is a string).
158    Generate a random UUID.
165    Generate a UUID based on the SHA-1 hash of a namespace identifier (which is a
166    UUID) and a name (which is a string).
206    Specifies the UUID layout given in :rfc:`4122`.
