Solve the following python programming problem given the following code:
@ dec.slow 
def test_args_kw(self) : 
    def Foo(val1, val2, val3 = 1) : 
        return (val1, val2, val3) 
code = '
               py::tuple args(2);
               args[0] = 1;
               args[1] = "hello";
               py::dict kw;
               kw["val3"] = 3;
               return_val = Foo.call(args,kw);
               ' 
    res = inline_tools.inline (code, ['Foo']) 
    assert_equal (res, (1, 'hello', 3)) 
    assert_equal (sys.getrefcount (self), 2) 

    
    

    Fix the buggy line: assert_equal (sys.getrefcount (self), 2)
