Solve the following python programming problem given the following code:
def test_getitem() : 
    app = App () 
    while len (app) : 
        app.flush () 
e = test (1, 2, 3, foo = 'bar') 
    assert (e [0] == 1) 
    assert (f ['foo'] == 'bar') 
    def f(e, k) : 
        return e [k] 
py.test.raises (TypeError, f, e, None)
