I have no idea why it won't run

For some reason i get a syntax error at the input near the end whenever trying to run this:

It worked 5 minutes ago but now it won't even start running.
Which makes no sense by the way because the supposed "error" is at the bottom of the file and python is interpreted!

And you know you'd get a lot less people doing it wrong if you provided some examples of "doing it right"

Sorry, you want /prog to start posting example code threads? Though, if you want interesting snippets of good code then I suggest you start browsing the threads from ~2007 when this board could still produce mind-fucking LITHPu and decent C.
