Why is there no uuid.uuid2 in Python?

Question

There's a uuid.uuid1, uuid.uuid3, uuid.uuid4, and uuid.uuid5 but no uuid.uuid2.

What happened to uuid2?

Answer 1

The UUID2 is a special UUID generated in combination with DCE Security server. It's rarely used nowadays. I guess the effort to implement that was in no relation to the request for such a functionality.

Answer 2

From What's new in Python 2.5 in which uuid module was added for the first time:

(Version 2 UUIDs are not specified in RFC 4122 and are not supported by this module.)
