Try with grep -P, which means use perl-compatible regexes as opposed to
POSIX ones. I only know for sure that -P exists for GNU grep.

I assumed it was a Python question! Unless you're testing your Python
regex with grep, not realizing they're different.

Perl and Python regexes are (mostly?) the same.

I usually grep -P because I know Python regexes better than any other
ones.
