Instead of generic Exception, it would be better to use AssertionError.

and

or in many cases given this was in unittests... use the self.assertFoo methods and avoid assert and if statements all together.

The code is running in a subprocess (python -c ...), not in an unittest.TestCase, so I cannot use self.assertFoo and it doesn't really matter if the exception is an Exception or an AssertionError.

What is the reason for this change anyway -- as far as I can see this code is never run with -O.

I'm not sure that the code will never be running using -O, so I prefer to use an explicit if+raise. I don't like the assert statement because it doesn't provide any information about the failure (content of the variables) by default.
