New submission from Chris Jerdonek <chris.jerdo...@gmail.com>: I think the generator.__next__() documentation should say that it raises an exception if the generator is already executing:
http://docs.python.org/dev/reference/expressions.html#generator.__next__ I don't think this is currently mentioned anywhere in the section on yield expressions. I think this is worth mentioning because this is different from the general situation for iterators, for example. One consequence of this is that, unlike for iterators, using a bare generator in a multithreaded situation will always result in a critical section (since an iterator can be made to take care of its own locking, etc). ---------- assignee: docs@python components: Documentation keywords: easy messages: 165476 nosy: cjerdonek, docs@python priority: normal severity: normal status: open title: generator.__next__() docs should mention exception if already executing versions: Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15355> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
