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 <ping@zesty.ca>)�win32�darwinFZAIXZLinuxz reserved for NCS compatibilityzspecified in RFC 4122z$reserved for Microsoft compatibilityz reserved for future definitionc @ s e Zd ZdZdZdZdS )�SafeUUIDr ���N)�__name__� __module__� __qualname__ZsafeZunsafe�unknown� r r �/usr/lib/python3.8/uuid.pyr H s r c @ s: e Zd ZdZdZd=ejd�dd�Zdd� Zd d � Z d d � Z d d� Z dd� Z dd� Z dd� Zdd� Zdd� Zdd� Zdd � Zd d � Zed d � �Zed!d"� �Zed#d$� �Zed%d&� �Zed'd(� �Zed)d*� �Zed+d,� �Zed-d.� �Z ed/d0� �Z ed1d2� �Z ed3d4� �Z ed5d6� �Z ed7d8� �Z!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). )�int�is_safe� __weakref__N)r c C s� |||||g� d�dkr td��|dk rl|�dd��dd�}|�d��dd�}t|�d krbtd ��t|d �}|dk r�t|�d kr�td ��|d dd� |dd d� |ddd� |dd� }|dk r�t|�d kr�td��t|t�s�t t |���tj |dd�}|dk �r*t|�dk�r td��|\}} } } } } d| k�rFdk �sPn td��d| k�rhdk �srn td��d| k�r�dk �s�n td ��d| k�r�d k �s�n td ��d| k�r�d k �s�n td ��d| k�r�d k �s�n td!��| d> | B }|d"> | d#> B | d$> B |d%> B | B }|dk �rZd| k�rPd&d'> k �sZn td(��|dk �r�d&| k�r|dk�s�n td)��|d*M }|d+O }|d,M }||d-> O }t � | d.|� t � | d/|� dS )0aL 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'. 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).
