Georg Brandl added the comment: Well, I guess Serhiy meant "neither increase nor decrease".
In the end, the exact behavior will never be clear if you don't state explicitly how it's implemented: a counter that starts at 0 and is increased on __next__ until it's equal to len(list) (as checked at every iteration step). But in general the advice should be: if you want to insert or remove elements during iteration, iterate over a copy. ---------- nosy: +georg.brandl _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16225> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
