Guido van Rossum <gu...@python.org> added the comment:
For sure the Python tokenizer/parser should reject octal escapes that produce values >= 256. Certainly in bytes strings. Probably also in text strings (nobody using Unicode thinks in octal). This is ancient behavior though (it's the same in 2.7) so it may require a deprecation for the text string case. (For byte strings, it should become an error in 3.9 -- dropping the top bit is nonsensical.) The regex parser should not be changed. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37367> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
