UUID objects are immutable, hashable, and usable as dictionary keys. Converting a UUID to a string with str() yields something in the form '12345678-1234-1234-1234-123456789abc'. The UUID constructor accepts five possible forms: a similar string of hexadecimal digits, or a tuple of six integer fields (with 32-bit, 16-bit, 16-bit, 8-bit, 8-bit, and 48-bit values respectively) as an argument named 'fields', or a string of 16 bytes (with all the integer fields in big-endian order) as an argument named 'bytes', or a string of 16 bytes (with the first three fields in little-endian order) as an argument named 'bytes_le', or a single 128-bit integer as an argument named 'int'. UUIDs have these read-only attributes: bytes the UUID as a 16-byte string (containing the six integer fields in big-endian byte order) bytes_le the UUID as a 16-byte string (with time_low, time_mid, and time_hi_version in little-endian byte order) fields a tuple of the six integer fields of the UUID, which are also available as six individual attributes and two derived attributes: time_low the first 32 bits of the UUID time_mid the next 16 bits of the UUID time_hi_version the next 16 bits of the UUID clock_seq_hi_variant the next 8 bits of the UUID clock_seq_low the next 8 bits of the UUID node the last 48 bits of the UUID time the 60-bit timestamp clock_seq the 14-bit sequence number hex the UUID as a 32-character hexadecimal string int the UUID as a 128-bit integer urn the UUID as a URN as specified in RFC 4122 variant the UUID variant (one of the constants RESERVED_NCS, RFC_4122, RESERVED_MICROSOFT, or RESERVED_FUTURE) version the UUID version number is_safe An enum indicating whether the UUID has been generated in a way that is safe for multiprocessing applications, via uuid_generate_time_safe(3). timestamp The timestamp of the UUID in milliseconds since epoch.
