New submission from Leon Hampton <leon_hamp...@yahoo.com>:
Hello, In the 3.7.7 documentation on Regular Expression, the Conditional Construct, (?(id/name)yes-pattern|no-pattern), is discussed. (This is a very thorough document, by the way. Good job!) One example given for the Conditional Construct does not work as described. Specifically, the example gives this matching pattern '(<)?(\w+@\w+(?:\.\w+)+)(?(1)>|$)' and states that it will NOT MATCH the string '<u...@host.com'. In my tests the pattern DOES MATCH that string. (The other examples work as described.) This may be a bug in re since it seems to me that the match should fail. Respectfully, Leon ---------- assignee: docs@python components: Documentation messages: 364811 nosy: LHampton, docs@python priority: normal severity: normal status: open title: Poor RegEx example for (?(id/name)yes-pattern|no-pattern) type: behavior versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40043> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
