Michael Selik added the comment: Yesterday I wanted to do a destructuring bind on a slice of groups in a finditer. Similar situation to the use case of Issue #24454. It might not be "normal code" but I end up in that situation every month or so when parsing semi-structured documents. I found myself wishing for a mapping-destructuring bind, but that's another story.
I haven't read the full discussion of ``len`` on MatchObject yet, but I tentatively agree with Brandon Rhodes' comment in Issue #19536: "My retort is that concentric groups can happen anyway: that Group Zero, holding the entire match, is not really as special as the newcomer might suspect, because you can always wind up with groups inside of other groups; it is simply part of the semantics of regular expressions that groups might overlap or might contain one another ..." @Serhiy, I was unaware of the feature of passing several arguments to groups. Unfortunately, the regex pattern I was using had a very large set of groups. A slice would have been particularly elegant. Passing several arguments to mo.groups() will be helpful, but still more awkward than a slice. Perhaps it is a can of worms, but I was pleased to see indexing available and was disappointed not to find the typically supported corresponding features. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29965> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
