So the slicing is actually just a copy (I realize that it has the side effect of checking whether it's a buffer or a producer). memoryview is also great to avoid copies when sending/receiving to a socket. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16787> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
