This module provides immutable UUID objects (class UUID) 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. Typical usage: >>> 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 '\x00\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f' # make a UUID from a 16-byte string >>> uuid.UUID(bytes=x.bytes) UUID('00010203-0405-0607-0809-0a0b0c0d0e0f') i����Ns Ka-Ping Yee <ping@zesty.ca>s reserved for NCS compatibilitys specified in RFC 4122s$ reserved for Microsoft compatibilitys reserved for future definitiont UUIDc B s� e Z d Z d d d d d d d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z e e � Z d � Z e e � Z d � Z e e � Z d � Z e e � Z d � Z e e � Z d � Z e e � Z d � Z e e � Z d � Z e e � Z d � Z e e � Z d � Z e e � Z d � Z e e � Z! d � Z" e e" � Z# d � Z$ e e$ � Z% d � Z& e e& � Z' d � Z( e e( � Z) RS( s� Instances of the UUID class represent UUIDs as specified in RFC 4122. 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 (1 through 5, meaningful only when the variant is RFC_4122) c C s� | | | | | g j d, � d k r3 t d � � n | d, k r� | j d d � j d d � } | j d � j d d � } t | � d k r� t d � � n t | d � } n | d, k r%t | � d k r� t d � � n | d | d | d | d | d | d | d | d | d } n | d, k r{t | � d k rRt d � � n t d d t t t | � � d � } n | d, k r�t | � d k r�t d � � n | \ } } } } } } d | k o�d- k n s�t d � � n d | k od. k n st d � � n d | k o-d/ k n sAt d � � n d | k oXd0 k n slt d � � n d | k o�d1 k n s�t d � � n d | k o�d2 k n s�t d � � n | d >| B} | d! >| d" >B| d# >B| d >B| B} n | d, k r3d | k o d3 k n s3t d% � � q3n | d, k r�d | k oVd k n sjt d& � � n | d5 M} | d6 O} | d8 M} | | d* >O} n | | j d+ <d, S(9 sm 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. When a string of hex digits is given, curly braces, hyphens, and a URN prefix are all optional. For example, these expressions all yield the same UUID: UUID('{12345678-1234-5678-1234-567812345678}') UUID('12345678123456781234567812345678') UUID('urn:uuid:12345678-1234-5678-1234-567812345678') UUID(bytes='\x12\x34\x56\x78'*4) UUID(bytes_le='\x78\x56\x34\x12\x34\x12\x78\x56' + '\x12\x34\x56\x78\x12\x34\x56\x78') UUID(fields=(0x12345678, 0x1234, 0x5678, 0x12, 0x34, 0x567812345678)) UUID(int=0x12345678123456781234567812345678) Exactly one of 'hex', 'bytes', 'bytes_le', 'fields', or 'int' must be given. The 'version' argument is optional; if given, the resulting UUID will have its variant and version set according to RFC 4122, overriding the given 'hex', 'bytes', 'bytes_le', 'fields', or 'int'. i s0 need one of hex, bytes, bytes_le, fields, or ints urn:t s uuid:s {}t -i s$ badly formed hexadecimal UUID stringi s bytes_le is not a 16-char stringi i i i i i i i s bytes is not a 16-char strings %02xs fields is not a 6-tuplel s* field 1 out of range (need a 32-bit value)l s* field 2 out of range (need a 16-bit value)s* field 3 out of range (need a 16-bit value)l s* field 4 out of range (need an 8-bit value)s* field 5 out of range (need an 8-bit value)l 0 s* field 6 out of range (need a 48-bit value)l ` l P l @ l � s* int is out of range (need a 128-bit value)s illegal version numberi � i � i � l L t intNl l l l l l l l l���� l l l���� ( t countt Nonet TypeErrort replacet stript lent ValueErrort longt tuplet mapt ordt __dict__( t selft hext bytest bytes_let fieldsR t versiont time_lowt time_midt time_hi_versiont clock_seq_hi_variantt clock_seq_lowt nodet clock_seq( ( s /usr/lib64/python2.7/uuid.pyt __init__g s\ $ ? ) ) c C s& t | t � r" t | j | j � St S( N( t isinstanceR t cmpR t NotImplemented( R t other( ( s /usr/lib64/python2.7/uuid.pyt __cmp__� s c C s t | j � S( N( t hashR ( R ( ( s /usr/lib64/python2.7/uuid.pyt __hash__� s c C s | j S( N( R ( R ( ( s /usr/lib64/python2.7/uuid.pyt __int__� s c C s d t | � S( Ns UUID(%r)( t str( R ( ( s /usr/lib64/python2.7/uuid.pyt __repr__� s c C s t d � � d S( Ns UUID objects are immutable( R ( R t namet value( ( s /usr/lib64/python2.7/uuid.pyt __setattr__� s c C sA d | j } d | d | d d !| d d !| d d !| d f S( Ns %032xs %s-%s-%s-%s-%si i i i ( R ( R R ( ( s /usr/lib64/python2.7/uuid.pyt __str__� s c C sB d } x5 t d d d � D]! } t | j | ?d @� | } q W| S( NR i i� i i� ( t ranget chrR ( R R t shift( ( s /usr/lib64/python2.7/uuid.pyt get_bytes� s c C sQ | j } | d | d | d | d | d | d | d | d | d S( Ni i i i i i i i i ( R ( R R ( ( s /usr/lib64/python2.7/uuid.pyt get_bytes_le� s c C s( | j | j | j | j | j | j f S( N( R R R R R R ( R ( ( s /usr/lib64/python2.7/uuid.pyt get_fields� s c C s | j d ?S( Nl ` ( R ( R ( ( s /usr/lib64/python2.7/uuid.pyt get_time_low� s c C s | j d ?d @S( Nl P i�� ( R ( R ( ( s /usr/lib64/python2.7/uuid.pyt get_time_mid� s c C s | j d ?d @S( Nl @ i�� ( R ( R ( ( s /usr/lib64/python2.7/uuid.pyt get_time_hi_version� s c C s | j d ?d @S( Nl 8 i� ( R ( R ( ( s /usr/lib64/python2.7/uuid.pyt get_clock_seq_hi_variant� s c C s | j d ?d @S( Nl 0 i� ( R ( R ( ( s /usr/lib64/python2.7/uuid.pyt get_clock_seq_low� s c C s! | j d @d >| j d >B| j BS( Nl �l 0 l ( R R R ( R ( ( s /usr/lib64/python2.7/uuid.pyt get_time� s c C s | j d @d >| j BS( Nl ? l ( R R ( R ( ( s /usr/lib64/python2.7/uuid.pyt get_clock_seq s c C s | j d @S( NI������ ( R ( R ( ( s /usr/lib64/python2.7/uuid.pyt get_node s c C s d | j S( Ns %032x( R ( R ( ( s /usr/lib64/python2.7/uuid.pyt get_hex s c C s d t | � S( Ns urn:uuid:( R& ( R ( ( s /usr/lib64/python2.7/uuid.pyt get_urn s c C s; | j d @s t S| j d @s" t S| j d @s3 t St Sd S( Ni � l 0 i @ i l l l ( R t RESERVED_NCSt RFC_4122t RESERVED_MICROSOFTt RESERVED_FUTURE( R ( ( s /usr/lib64/python2.7/uuid.pyt get_variant s c C s( | j t k r$ t | j d ?d @� Sd S( Nl L i ( t variantR= R ( R ( ( s /usr/lib64/python2.7/uuid.pyt get_version! s N(* t __name__t __module__t __doc__R R R" R$ R% R' R* R+ R/ t propertyR R0 R R1 R R2 R R3 R R4 R R5 R R6 R R7 t timeR8 R R9 R R: R R; t urnR@ RA RB R ( ( ( s /usr/lib64/python2.7/uuid.pyR 7 sN .
