Right. It raises a SyntaxError because you've got a simple string
literal that isn't closed before the end of the line.

What behaviour would you expect from that? We can't guess what you mean
by “get it to work” unless we know what you're expecting and how the
observed behaviour is different.
A good way to do this would be to show some actual code that
demonstrates the surprising behaviour (you may need to post using a
service that doesn't munge your text), along with the traceback if any.
Then, show a session that behaves the way you'd expect it to behave, and
we can explain either how to achieve that or why it can't.
