[issue14167] document return statement in finally blocks
Mark Dickinson added the comment: I think something went wrong with this doc change. The docs used to say: If the :keyword:`finally` clause raises another exception or executes a :keyword:`return` or :keyword:`break` statement, the saved exception is lost. Now we have: If there is a saved exception or :keyword:`break` statement, it is re-raised at the end of the :keyword:`finally` clause. which doesn't make much sense (what does 'it' refer to in the case of a 'break' statement), and we seem to have lost the explicit statement that a 'break' in a finally cause swallows exceptions. -- nosy: +mark.dickinson ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14167 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

New submission from Yury Selivanov yseliva...@gmail.com: I think that the documentation should put more emphasis on the `return` statement in a `finally` block. Example: def test(): try: 1/0 finally: return 10 test() 10 I think we need to add a warning, or at least a note, that 'return' masks exceptions, if any occurred. -- assignee: docs@python components: Documentation messages: 154697 nosy: Yury.Selivanov, docs@python, georg.brandl, rhettinger priority: normal severity: normal status: open title: document return statement in finally blocks type: enhancement versions: Python 2.7, Python 3.2 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14167 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
