SyntaxError: invalid syntax

Ha, the result of course, that I can go on and did a great job.

I am stuck with this. I checked posts in the forum yesterday, I slept a night over it and re-checked today again. But can't find what's wrong. Unfortunately it seems I am already blind to this code. So, my hope is, that a pair of fresh eyes can find the error and help me. Thanks.
