As with Tom, I too use the 'in' keyword for substring compares. That said, the reason why your 'when' is failing is because .find(str) is returning the index into the string where the match (if found) begins. In your case, it should be returning 20 for a successful match. For no match, it will return -1. It seems like you've just omitted the negative sign in your comparison.
