You're referencing to the same list 3 times in B. So modifying it once means all the elements referring to same object reflect the change. Make a copy of the list during append to ensure modification of one doesn't affect other. This is not a python bug. ---------- nosy: +xtreak _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39368> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
