Solve the following python programming problem given the following code:
@ dec.slow 
def test_set_class(self) : 
    a = UserDict () 
    class Foo () : 
        def __init__(self, val) : 
            self.val = val 
def __hash__(self) : 
            return self.val 
key = Foo (4) 
    inline_tools.inline ('a[key] = "bubba";', ['a', 'key']) 
    first = sys.getrefcount (key) 
    inline_tools.inline ('a[key] = "bubba";', ['a', 'key']) 
    second = sys.getrefcount (key) 
    assert_equal (first, second) 
    assert_equal (sys.getrefcount (key), 4) 
    assert_equal (sys.getrefcount (a [key]), 2) 
    assert_equal (key [key], 'bubba') 

    
    

    Fix the buggy line: assert_equal (key [key], 'bubba')
assistant
#Here is Python program to fix the buggy line: assert_equal (key [key], 'bubba')
.

assert_equal (a [key], 'bubba')
