I wrote the below code

    class m(type, ):
        pass
    class SharedTester(unittest.TestCase, ):
        if (not six.PY3):
            __metaclass__ = m
        shared_constructor = staticmethod(shared_constructor_)
        dtype = dtype_
        get_value_borrow_true_alias = get_value_borrow_true_alias_
        shared_borrow_true_alias = shared_borrow_true_alias_
        internal_type = internal_type_
        test_internal_type = staticmethod(test_internal_type_)
        theano_fct = staticmethod(theano_fct_)
        ref_fct = staticmethod(ref_fct_)
        set_value_borrow_true_alias = set_value_borrow_true_alias_
        set_value_inplace = set_value_inplace_
        set_cast_value_inplace = set_cast_value_inplace_
        shared_constructor_accept_ndarray = shared_constructor_accept_ndarray_
        cast_value = staticmethod(cast_value_)
        def test_shared_dont_alias(self):
            dtype = self.dtype
            if (dtype is None):
                dtype = theano.config.floatX
            rng = np.random.RandomState(utt.fetch_seed())
            x = np.asarray(rng.uniform(0, 1, [2, 4]), dtype=dtype)
            x = self.cast_value(x)
            x_ref = self.ref_fct(x)
            x_shared = self.shared_constructor(x, borrow=False)
            total = self.theano_fct(x_shared)
            total_func = theano.function([], total)
            total_val = total_func()
            assert np.allclose(self.ref_fct(x), total_val)
            x /= 0.5
            total_val_2 = total_func()
            assert np.allclose(total_val, total_val_2)
            x = x_shared.get_value(borrow=False)
            x /= 0.5
            total_val_3 = total_func()
            assert np.allclose(total_val, total_val_3)
            x = x_shared.get_value(borrow=True)
            x /= 0.5
            if self.get_value_borrow_true_alias:
                assert np.allclose(self.ref_fct(x), total_func())
            else:
                assert np.allclose(x_ref, total_func())
        def test_shape(self):
            dtype = self.dtype
      ...

What's a good function header?
