> something[::-1] = something I was thinking this for a while, and this is the actual reason that I didn't propose this until I saw someone's comment under Raymond's tweet about 'slices are not hashable' (https://twitter.com/4skvictor/status/1330433911646785539). At least for optimization, IMHO it worth taking the shot. > I could definitely see code using duck-typing via slices to distinguish > sequences from other iterables and mappings That sounds a bit unorthodox. It is a very common practice to use ABCs for doing these checks but I've never seen a piece of code where they test if something is a mapping or not by throwing unhashable things in it. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42454> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
