While the other responses have addressed some of the big issues,
it's also good to use

if thing_to_test is not None:

I would like to thank all of you for your responses. I understand
what the regular expression means, and am aware of the double negative
nature of the test. I guess what I am really getting at is why the
last test returns a value of None, and even when using the syntax
suggested in this quoted solution, the code for the last test is doing
the opposite of the previous 2 tests that also returned a value of
None. I hope this makes sense and clarifies what I am trying to ask.
It returns None because it doesn't match.
Why doesn't it match?
Because the regex wants the last character to be a 'y', but it isn't,
it's a 'a'.
