To be more precise, the code looks like this:

     if (PyCallable_Check(template)) {
         /* sub/subn takes either a function or a template */
         filter = template;
         Py_INCREF(filter);
         filter_is_callable = 1;
     } else {
         /* if not callable, check if it's a literal string */

It's in the pattern_subx function of _sre.c, which you can
find in the Python source code.
