Not sure what the specific use case is, but I think I would use
PyString_Format instead, and use everything you can use in a %
operator. If you want to avoid explicit argument tuple building,
you can also write

  static PyObject *fmt = NULL;
  if (!fmt) fmt = PyString_FromString("Foo %s bar %s foobar %d");
  res = PyMethod_Call(fmt, "__mod__", "(OOi)", o1, o2, 42);
