The first 8 bytes, however, seem to come from clock. so if > this is called multiple times in a short time period, two ids will likely > collide. > _uuid.uuid4_ provides random values. > {code} > Python 2.7.15 (default, Jun 17 2018, 12:46:58) > [GCC 4.2.1 Compatible Apple LLVM 9.1.0 (clang-902.0.39.2)] on darwin > Type "help", "copyright", "credits" or "license" for more information. > >>> import uuid > >>> for i in range(10): > ... uuid.uuid1() > ... > UUID('e8bc9959-a586-11e8-ab8c-8c859010d0c2') > UUID('e8c254e3-a586-11e8-ac39-8c859010d0c2') > UUID('e8c2560f-a586-11e8-8251-8c859010d0c2') > UUID('e8c256c2-a586-11e8-994a-8c859010d0c2') > UUID('e8c25759-a586-11e8-9ba6-8c859010d0c2') > UUID('e8c257e6-a586-11e8-a854-8c859010d0c2') > UUID('e8c2587d-a586-11e8-89e9-8c859010d0c2') > UUID('e8c2590a-a586-11e8-a825-8c859010d0c2') > UUID('e8c25994-a586-11e8-9421-8c859010d0c2') > UUID('e8c25a21-a586-11e8-83fd-8c859010d0c2') > >>> for i in range(10): > ... uuid.uuid4() > ... > UUID('f1eba69f-18ea-467e-a414-b18d67f34a51') > UUID('aaa4e18e-d4e6-42c9-905c-3cde714c2741') > UUID('82f55c27-69ae-474b-ab9a-afcc7891587c') > UUID('fab63643-ad33-4307-837b-68444fce7240') > UUID('c4efca6c-3d1b-436c-8b09-e9b7f55ccefb') > UUID('58de3a76-9d98-4427-8232-d6d7df2a1904') > UUID('4f0a55e8-1357-4697-a345-e60891685b00') > UUID('0fed47a3-07b6-423e-ae2e-d821c440cb63') > UUID('144b2c55-a9bd-431d-b536-239fb2048a5e') > UUID('d47fd8a0-48e9-4dcc-87f7-42c022c309a8') > {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
