UUID.bytes The UUID as a 16-byte string (containing the six integer fields in big-endian byte order).

UUID.urn The UUID as a URN as specified in RFC 4122.

UUID.fields A tuple of the six integer fields of the UUID, which are also available as six individual attributes and two derived attributes: Field Meaning 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

UUID.variant The UUID variant, which determines the internal layout of the UUID. This will be one of the integer constants RESERVED_NCS, RFC_4122, RESERVED_MICROSOFT, or RESERVED_FUTURE.

UUID.bytes_le The UUID as a 16-byte string (with time_low, time_mid, and time_hi_version in little-endian byte order).

UUID.hex The UUID as a 32-character hexadecimal string.

UUID.int The UUID as a 128-bit integer.

exception uu.Error Subclass of Exception, this can be raised by uu.decode() under various situations, such as described above, but also including a badly formatted header, or truncated input file.

exception UserWarning Base class for warnings generated by user code.

class uuid.UUID(hex=None, bytes=None, bytes_le=None, fields=None, int=None, version=None) Create a UUID from either a string of 32 hexadecimal digits, a string of 16 bytes as the bytes argument, a string of 16 bytes in little-endian order as the bytes_le argument, a tuple of six integers (32-bit time_low, 16-bit time_mid, 16-bit time_hi_version, 8-bit clock_seq_hi_variant, 8-bit clock_seq_low, 48-bit node) as the fields argument, or a single 128-bit integer as the int argument.
