book book <book78987book@gmail.com> added the comment: tp_del still undocumented. In my opinion, tp_del corresponds to the __del__() method of classes, because there are no other variable correspondes to it, but methods using for creating(tp_new) and initializing(tp_init) an object are not. Although __del__ method have some issue according to the offical document, but it is exist, so there must have a pointer to the function corresponding to it. ---------- nosy: +book book versions: +Python 3.6 -Python 2.6, Python 2.7, Python 3.2, Python 3.3, Python 3.4 _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue4934> _______________________________________
