New submission from Emanuel Barry <ba...@dadadata.net>: This is a follow-up to Issue27364.
Back in Python 3.6, a silent warning was added for all invalid escape sequences in str and bytes. It was suggested that it would remain a silent warning (which still impacts tests, while not visually annoying the average user) for two releases (3.6 and 3.7), then would be upgraded to a non-silent warning for two subsequent releases (3.8 and 3.9) before becoming a full-on syntax error. With the 3.7 feature freeze on and going, I think it's time to evaluate the approach we take for 3.8 :) I suggest upgrading the DeprecationWarning to a SyntaxWarning, which is visible by default, for 3.8 and 3.9. I have cross-linked #27364 to this issue as well. -Em ---------- components: Interpreter Core messages: 312575 nosy: ebarry priority: normal severity: normal stage: needs patch status: open title: Raise non-silent warning for invalid escape sequences type: behavior versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32912> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
