New submission from merelymoray <arcadesrofocale@yahoo.co.uk>: https://docs.python.org/3.6/library/uuid.html#uuid.UUID uuid.uuid1(node=None, clock_seq=None) Generate a UUID from a host ID, sequence number, and the current time. If node is not given, getnode() is used to obtain the hardware address. If clock_seq is given, it is used as the sequence number; otherwise a random 14-bit sequence number is chosen. ^^ This neglects to mention that if you call uuid1() in quick succession with no parameters, you can get a repeat uuid. I had a bug because of this. It would have been nice if the docs mentioned the fact directly. It's only a sentence to add, and would have saved a lot of time. ---------- assignee: docs@python components: Documentation messages: 316844 nosy: docs@python, merelymoray priority: normal severity: normal status: open title: Docs for uuid don't mention that uuid1 can repeat in some circumstances type: enhancement versions: Python 3.6 _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue33545> _______________________________________
