  from re import sub, findall

That's where pcre2 is called (or a finely tuned regex c lib)

re is an ordinary standard Python library —

pcre2 is not —

And? CPython is implemented in C.

Here's some of a comment from _operator.c

"This module exports a set of functions implemented in C corresponding\n\ to the intrinsic operators of Python. For example, operator.add(x, y)\n\ is equivalent to the expression x+y."

Why wouldn't you expect that CPython regex would "ultimately" be written in C?
