Solve the following python programming problem given the following code:
@ patch ('mock.patch.TEST_PREFIX', 'bar') 
def test_patch_dict_test_prefix(self) : 
    class Foo (object) : 
        def bar_one(self) : 
            return dict (the_dict) 
def bar_two(self) : 
            return dict (the_dict) 
def test_one(self) : 
            return dict (the_dict) 
def test_two(self) : 
            return dict (the_dict) 
the_dict = { 
        'key' : 'original', 
} 
    Foo = patch.dict (the_dict, key = 'changed') (foo) 
    foo = Foo () 
    self.assertEqual (foo.bar_one (), { 
        'key' : 'changed', 
}) 
    self.assertEqual (foo.bar_two (), { 
        'key' : 'changed', 
}) 
    self.assertEqual (foo.test_one (), { 
        'key' : 'original', 
}) 
    self.assertEqual (foo.test_two (), { 
        'key' : 'original', 
}) 

    
    

    Fix the buggy line: Foo = patch.dict (the_dict, key = 'changed') (foo)
assistant
#Here is Python code to fix the buggy line: Foo = patch.

Foo = patch.dict (the_dict, key = 'changed') (Foo)
