I tried to remove list(), and just use cmd like `_ = d[0:1]`, and it surprisingly changed d[0].owner from d to d[0:1]! The file attached is updated. I pretty sure that it is a (serious) bug. Please check it more carefully. Thanks. ---------- title: UserList-subclass Tree slicing changes node attribute -> UserList-subclass Tree slicing changes the original list unexpectedly Added file: https://bugs.python.org/file48799/bug.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39110> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
