This is a common mistake, you'll find the FAQ entry for it here: https://docs.python.org/3/faq/programming.html#why-are-default-values-shared-between-objects It's not necessarily a "feature" but default values in functions are only created once, when the function is defined. Subsequent calls will refer to that same initially created object. ---------- nosy: +ammar2 resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39556> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
