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') sKa-Ping Yee sreserved for NCS compatibilitysspecified in RFC 4122s$reserved for Microsoft compatibilitysreserved for future definitiontUUIDcBseZdZdddddddZdZdZdZdZdZ dZ dZ e e Z d Ze eZd Ze eZd Ze eZd Ze eZd Ze eZdZe eZdZe eZdZe eZdZe eZdZ e e Z!dZ"e e"Z#dZ$e e$Z%dZ&e e&Z'dZ(e e(Z)RS(sInstances 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 Cs|||||gjd,dkr3tdn|d,k r|jddjdd}|jdjdd}t|dkrtd nt|d }n|d,k r%t|d krtd n|d |d |d|d|d|d|d|d|d}n|d,k r{t|d krRtdntdd tt t |d }n|d,k rt|dkrtdn|\}}} } } } d|kod-knstdnd|kod.knstdnd| ko-d/knsAtdnd| koXd0knsltdnd| kod1knstdnd| kod2knstd n| d>| B} |d!>|d">B| d#>B| d>B| B}n|d,k r3d|kod3kns3td%q3n|d,k rd|koVdknsjtd&n|d5M}|d6O}|d8M}||d*>O}n||j d+|jd>B|jBS(Nll0l (RRR(R((s/usr/lib/python2.7/uuid.pytget_timescCs|jd@d>|jBS(Nl?l(RR(R((s/usr/lib/python2.7/uuid.pyt get_clock_seqscCs |jd@S(Nl(R(R((s/usr/lib/python2.7/uuid.pytget_nodescCs d|jS(Ns%032x(R(R((s/usr/lib/python2.7/uuid.pytget_hex scCsdt|S(Ns urn:uuid:(R&(R((s/usr/lib/python2.7/uuid.pytget_urnscCs;|jd@stS|jd@s"tS|jd@s3tStSdS(Nil0i@i lll(Rt RESERVED_NCStRFC_4122tRESERVED_MICROSOFTtRESERVED_FUTURE(R((s/usr/lib/python2.7/uuid.pyt get_variants   cCs(|jtkr$t|jd?d@SdS(NlLi(tvariantR=R(R((s/usr/lib/python2.7/uuid.pyt get_versionsN(*t__name__t __module__t__doc__RRR"R$R%R'R*R+R/tpropertyRR0RR1RR2RR3RR4RR5RR6RR7ttimeR8RR9RR:RR;turnR@RARBR(((s/usr/lib/python2.7/uuid.pyR5sN.
