objects (universally unique identifiers) according to .
This module provides immutable objects (class ) and the functions
(), (), (), () for generating version 1, 3, 4, and 5
UUIDs as specified in .
If all you want is a unique ID, you should probably call () or ().
Note that () may compromise privacy since it creates a containing
the computer's network address. () creates a random .
Typical usage:
>>> import uuid
# make a based on the host ID and current time
>>> uuid.()
('a8098c1a-f86e-11da-bd1a-00112444be1e')
# make a using an MD5 hash of a namespace and a name
>>> uuid.(uuid.NAMESPACE_DNS, 'python.org')
('6fa459ea-ee8a-3ca4-894e-db77e160355e')
# make a random
>>> uuid.()
('16fd2706-8baf-433b-82eb-8c7fada847da')
# make a using a SHA-1 hash of a namespace and a name
>>> uuid.(uuid.NAMESPACE_DNS, 'python.org')
('886313e1-3b8a-5372-9b90-0c9aee199e5d')
# make a from a string of hex digits (braces and hyphens ignored)
>>> x = uuid.('{00010203-0405-0607-0809-0a0b0c0d0e0f}')
# convert a to a string of hex digits in standard form
>>> str(x)
'00010203-0405-0607-0809-0a0b0c0d0e0f'
# get the raw 16 bytes of the
>>> x.bytes
'\x00\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f'
# make a from a 16-byte string
>>> uuid.(bytes=x.bytes)
('00010203-0405-0607-0809-0a0b0c0d0e0f')
This module works with Python 2.3 or higher.
