Well even if it had been right, I omitted one (backslash). I'm such a newb/hack. lol. No animals were harmed.
Yeah, I have noticed that they don't seem to be needed, but I think I remember reading "someplace-somewhere" that a backslash means a line continuation, and perhaps I saw some author put them in. So I did it out of trying to be "strict."
I'm not sure when a backslash continuation might be needed, or if that requirement has been designed out of Python.
Anyway, thanks to all for the notes!
