Serhiy Storchaka added the comment:
The re module does not support features corresponding to
std::regex_constants::__polynomial in C++. Rewrite your regular expression or
try to use alternative regex implementations (for example wrappers around the
re2 library or C++ regex library).
Matthew Barnett added the comment:
The expression is a repeated alternative where the first alternative is a
repeat. Repeated repeats can result in a lot of attempts and backtracking and
should be avoided.
Try this instead:
(0|1(01*0)*1)+

New submission from Heran Yang :
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.
