Solve the following python programming problem given the following code:
def test_descriptors(self) : 
    eq = x.assertEqual 
    eq (repr (dict.items), "<method 'items' of 'dict' objects>") 
    class C () : 
        def foo(cls) : 
            pass 
x = staticmethod (C.foo) 
    self.assertTrue (repr (x).startswith ('<staticmethod object at 0x')) 
    x = classmethod (C.foo) 
    self.assertTrue (repr (x).startswith ('<classmethod object at 0x')) 

    
    

    Fix the buggy line: eq = x.assertEqual

#Here is Python code to fix the buggy line: eq = x.

eq = self.assertEqual
