Armin Rigo added the comment: Ok, then with pickle you can have the same problem but only with None-vs-no-total. Here is an artificial example:
import itertools, pickle def foo(a, b): print(a, b) a = itertools.accumulate([3, 4, 5], foo) next(a) next(a) # prints: 3, 4 b = pickle.loads(pickle.dumps(a)) next(a) # prints: None, 5 next(b) # foo() is not called at all ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25718> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
