我们从Python开源项目中，提取了以下32个代码示例，用于说明如何使用tornado.gen.Arguments()。
def test_arguments(self): @gen.engine def f(): (yield gen.Callback("noargs"))() self.assertEqual((yield gen.Wait("noargs")), None) (yield gen.Callback("1arg"))(42) self.assertEqual((yield gen.Wait("1arg")), 42) (yield gen.Callback("kwargs"))(value=42) result = yield gen.Wait("kwargs") self.assertTrue(isinstance(result, gen.Arguments)) self.assertEqual(((), dict(value=42)), result) self.assertEqual(dict(value=42), result.kwargs) (yield gen.Callback("2args"))(42, 43) result = yield gen.Wait("2args") self.assertTrue(isinstance(result, gen.Arguments)) self.assertEqual(((42, 43), {}), result) self.assertEqual((42, 43), result.args) def task_func(callback): callback(None, error="foo") result = yield gen.Task(task_func) self.assertTrue(isinstance(result, gen.Arguments)) self.assertEqual(((None,), dict(error="foo")), result) self.stop() self.run_gen(f)
