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() # doctest: +SKIP 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() # doctest: +SKIP 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 b'\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') zKa-Ping Yee zreserved for NCS compatibilityzspecified in RFC 4122z$reserved for Microsoft compatibilityzreserved for future definitionc@seZdZdZddddddddZddZddZd d Zd d Zd dZ ddZ ddZ ddZ ddZ ddZddZeddZeddZedd Zed!d"Zed#d$Zed%d&Zed'd(Zed)d*Zed+d,Zed-d.Zed/d0Zed1d2Zed3d4Zed5d6Zed7d8ZdS)9UUIDaInstances 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) NcCs|||||gjddkr3tdn|dk r|jddjdd}|jdjdd}t|d krtd nt|d }n|dk r9t|d krtd ntt|d dtt|ddtt|dd|dd}n|dk r~t|d krftdntj |dd}n|dk rt|dkrtdn|\}}} } } } d |kod(knstdnd |kod)knstdnd | ko0d*knsDtdnd | ko[d+knsotdnd | kod,knstdnd | kod-knstdn| d>| B} |d>|d>B| d>B| d>B| B}n|dk r6d |kod.kns6td q6n|dk rd|koYd!knsmtd"n|d0M}|d1O}|d3M}||d&>O}n||j d'|jd>B|jBS)Nir r)r(r'r&)r r-r-r.timesz UUID.timecCs|jd@d>|jBS)N?r )r)r*)r r-r-r.r,szUUID.clock_seqcCs |jd@S)Nl)r)r r-r-r.r+sz UUID.nodecCs d|jS)Nz%032x)r)r r-r-r.r!!szUUID.hexcCsdt|S)Nz urn:uuid:)r<)r r-r-r.urn%szUUID.urncCs;|jd@stS|jd@s"tS|jd@s3tStSdS)Nir i@i lll)r RESERVED_NCSRFC_4122RESERVED_MICROSOFTRESERVED_FUTURE)r r-r-r.variant)s   z UUID.variantcCs(|jtkr$t|jd?d@SdS)Nr)rPrMr)r r-r-r.r%4sz UUID.version) __name__ __module__ __qualname____doc__r/r3r4r5r6r7r8r:r;r=r@rCpropertyr"r#r$r&r'r(r)r*rIr,r+r!rKrPr%r-r-r-r.r8s: .
