Terry J. Reedy <tjre...@udel.edu> added the comment:
Subscription of list and dict (only with '') and ??? is at least puzzling. Removal of a new feature after release is a bad idea. But this new feature, expansion of subscription, needs to documented in https://docs.python.org/3/reference/expressions.html#subscriptions as legal code. The current first line "A subscription selects an item of a sequence (string, tuple or list) or mapping (dictionary) object:" is no longer always true. This suggested replacement is: "Subscription of a sequence (string, tuple or list) or mapping (dictionary) object selects an item from the collection." Then at the end, add something like "Subscription of certain type objects creates a Generic Alias. where 'Generic Alias links to where such are documented. ---------- assignee: -> docs@python components: +Documentation -Interpreter Core nosy: +docs@python, terry.reedy stage: patch review -> needs patch _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42010> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
