New submission from Heran Yang <hera...@126.com>:
I'm using `re.fullmatch` to match a string that only contains 0 and 1. The regular expression is: (0+|1(01*0)*1)+ It runs rather slow with Python 3.7, but when I try using regex in C++, with std::regex_constants::__polynomial, it works well. Would someone take a look at it? Thx. ---------- components: Regular Expressions files: match.py messages: 413700 nosy: HeRaNO, ezio.melotti, mrabarnett priority: normal severity: normal status: open title: slow matching on regular expression type: performance versions: Python 3.7 Added file: https://bugs.python.org/file50636/match.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46825> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
