New submission from zeroswan <zeros...@outlook.com>: I find it's a valid expression: `1 in [1, 2, 3] in [4, 5, 6]`
`a in b in c` is equivalent to `a in b and b in c` but this expression seems useless, and easy to confused with (a in b) in c . in this program, what I originally want is `if a in b and a in c` , But it was mistakenly written as `a in b in c` This expression is similar to `a<b<c` 。 But it seems very unreasonable here, is this a bug ? ---------- components: Parser messages: 402478 nosy: lys.nikolaou, pablogsal, weditor priority: normal severity: normal status: open title: use multiple "in" in one expression? type: behavior versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45268> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
