New submission from Julien Palard <julien+pyt...@palard.fr>:
In [1] I read: > If the target list is a comma-separated list of targets, or a single target > in square brackets This come from https://bugs.python.org/issue23275 (patch is [2]). I suspect there's a missing case "list of targets in square brackets" (and to be pedantic "list of targets in parenthesis"). The specialized documentation about single-valued targets in sequence-like construction come from this difference: >>> (a) = 42 >>> a 42 >>> [a] = [42] >>> a 42 which is correctly described the line before: > If the target list is a single target in parentheses: The object is assigned > to that target. So the correct way to state it may be: > Else the object must be an iterable with the same number of items as there > are targets in the target list, and the items are assigned, from left to > right, to the corresponding targets. The `Else`, coupled with the existing "Assignment of an object to a target list, optionally enclosed in parentheses or square brackets" covers properly the cases: - Multiple target separated by comas (already covered) - Multiple target enclosed by parenthesis and brackets (not covered) - Single target enclosed by angle brackets (already covered) [1]: https://docs.python.org/3.7/reference/simple_stmts.html#assignment-statements [2]: https://bugs.python.org/file42878/issue23275_v4.diff ---------- assignee: docs@python components: Documentation messages: 319735 nosy: docs@python, martin.panter, mdk priority: normal severity: normal status: open title: Doc: Assignment statement to tuple or list: case missing. type: enhancement _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33878> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
