Actually, that last line will more like

At least, if what you posted above is accurate...

It's not the question you asked, but if you want to make that easier
to read, you can do something like

   PyRun_SimpleString("import grabber");
   PyRun_SimpleString("import sys");

   PyRun_SimpleString("class a:\n"
                      "   def write(self,s):\n"
                      "      grabber.grab(s)\n");

   PyRun_SimpleString("import sys\n"
                      "sys.stderr=a()\n"
                      "sys.stdout=a()\n");


C++, like Python, will concatenate strings seperated only by
whitespace.
