Solve the following python programming problem given the following code:
@ skipif ((sys.version_info < (3,)), reason = 'not Python 3.x') 
def test_functiondef_some_more() : 
    code = "
    def foo(a, b=3, *, c=4, d):
        pass
    def bar(a:[], b:(1,2), *c:'xx', **d:'yy') -> 'returns':
        pass
    " 
    code = '
'.join ((x [4 :] for x in code.splitlines ())) 
    root = commonast.parse (code) 
    assert (len (root.body_nodes) == 2) 
    (f1, f2) = root.body_nodes 
    assert isinstance (f1, commonast.FunctionDef) 
    assert isinstance (f2, commonast.FunctionDef) 
    assert (len (f1.arg_nodes) == 2) 
    assert (len (f1.kwarg_nodes) == 2) 
    for (arg, name) in zip ((f1.arg_nodes + f1.kwarg_nodes), 'abcd') : 
        assert isinstance (arg, commonast.Arg) 
        assert (arg.name == name) 
        assert (arg.annotation_node is None) 
assert (f1.arg_nodes [0].value_node is None) 
    assert (f1.arg_nodes [1].value_node.value == 3) 
    assert (f1.kwarg_nodes [0].value_node.value == 4) 
    assert (f1.kwarg_nodes [1].value_node is None) 
    assert (len (f2.arg_nodes) == 2) 
    assert (len (name.kwarg_nodes) == 0) 
    for (arg, name) in zip ((f2.arg_nodes + [f2.args_node, f2.kwargs_node]), 'abcd') : 
        assert isinstance (arg, commonast.Arg)

    Fix the buggy line: assert (len (name.kwarg_nodes) == 0)

#Here is Python program to fix the buggy line: assert (len (name.

assert (len (f2.kwarg_nodes) == 0)
