New submission from Vladimir Ryabtsev <greatvo...@gmail.com>:
A new section has been added to the page as a result of https://bugs.python.org/issue37826. The change: https://github.com/python/cpython/commit/dcfe111eb5602333135b8776996332a8dcf59392 The wording it uses (in the beginning of section 8.5), defines chaining as setting __cause__ attribute in an exception, and later states that "Exception chaining happens automatically when an exception is raised inside an exception handler or finally section". This may lead the reader to a wrong idea that re-raising an exception without "from" in "except" and "finally" automatically sets __cause__. In reality it sets only __context__ attribute, which is similar concept to __cause__, but work a bit differently, as explained in library/exceptions.rst. I suggest to mention that difference and provide a link to the main article. ---------- assignee: docs@python components: Documentation messages: 379823 nosy: Vladimir Ryabtsev, docs@python priority: normal severity: normal status: open title: Clarify chaining exceptions in tutorial/errors.rst versions: Python 3.10, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42179> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
