Think about what it means to iterate over a hashmap. Let's say your pop() causes the dictionary to become smaller than the resizing threshold and now the indexes need to be rebuilt, how would this be handled gently by the iterator? This situation is not just something unique to python dictionaries, google around for "delete while iterating" and you'll find that most languages prohibit you from mutating containers while iterating over them. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35023> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
