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') N)EnumzKa-Ping Yee )win32darwinFZAIXZLinuxzreserved for NCS compatibilityzspecified in RFC 4122z$reserved for Microsoft compatibilityzreserved for future definitionc@seZdZdZdZdZdS)SafeUUIDrN)__name__ __module__ __qualname__ZsafeZunsafeunknownr r /usr/lib64/python3.8/uuid.pyrHsrc@s:eZdZdZdZd=ejdddZddZd d Z d d Z d dZ ddZ ddZ ddZddZddZddZddZddZedd Zed!d"Zed#d$Zed%d&Zed'd(Zed)d*Zed+d,Zed-d.Zed/d0Zed1d2Zed3d4Zed5d6Z ed7d8Z!ed9d:Z"ed;d<Z#dS)>UUIDa 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) 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). )intis_safe __weakref__N)rcCs|||||gddkr td|dk rl|dddd}|ddd}t|d krbtd t|d }|dk rt|d krtd |d dd|dd d|ddd|dd}|dk rt|d krtdtj|dd}|dk rt|dkrtd|\}} } } } } d|kr0dks:ntdd| krRdks\ntdd| krtdks~ntdd| krdksntdd| krdksntdd| krd ksntd!| d>| B}|d">| d#>B| d$>B|d%>B| B}|dk rDd|kr:d&d'>ksDntd(|dk rd&|krfdkspntd)|d*M}|d+O}|d,M}||d->O}t |d.|t |d/|dS)0aLCreate 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'. is_safe is an enum exposed as an attribute on the instance. It indicates whether the UUID has been generated in a way that is safe for multiprocessing applications, via uuid_generate_time_safe(3).
