[Tutor] Questions as to how to run the same unit test multiple times on varying input data.

loop to work inside the class, but I guess my current poor knowledge of OOP did me in. But I KNOW there has to be a way to accomplish this WITHOUT using subTest. After all, subTest was not introduced until Python 3.4. So how should I go about this without using subTest? Question #3: In "with self.subTest(test_string = test_string):" why is "test_string = test_string" necessary? Is it that using "with" sets up a new local namespace within this context manager?
